1 Gray Balance Process Control Easy, Practical, Effective

The aim o process control at press side is to quickly achieve the desired

color results. When the more important press parameters, such as stan-

dardized plate production, dot gain, paper and ink have been deter-

mined, then it wont take very long to balance the inking or the best pos-

sible outcome.

The ECI/bvdm Gray Control Strip has been developed or printers as an

aid to help balance the press process in the best way possible by utilizing

a standardized proo. Thats why the ECI/bvdm Gray Control Strip is

based on the same color characterization data that are used in industry

standard ICC proles (or example, the ECI proles) and the Ugra/FograCMYK Media Wedge in prepress. ECI oset proles are based on color

characterization data rom Fogra.

2 The ECI/bvdm Gray Control Strip

Gray balance patches that allow a quick and convenient visual control are

good aids or accurate inking. Thats why the ECI/bvdm Gray Control

Strip relies on this one simple rule: Chromatic gray (CMY) has to look

exactly like true gray (K).

The aim is thereore, to match the ECI/bvdm Gray Control Strip chromatic

gray patches to the true gray patches by controlled inking. That is, the

technical tone consisting o dened cyan, magenta and yellow (chromatic

gray) values is compared to a tone value that consists o pure black (true

gray). By balancing out the colors at the press, two patches that consist

o two dierent sets o values ideally end up looking the same.

The Human Eye as Metering Device

Because the human eye is well suited in comparing colors that are

directly adjacent to each other, and in particular are very sensitive in

detecting color dierences within the gray zone, they serve as a visual

metering device when using the ECI/bvdm Gray Control Strip or assess-

ment. By visually controlling the gray balance patches, deviations in ink-

ing can be recognized and corrected in due time press side, beore these

have a chance to show up on the printed image. Yet visually controlling

the gray balance in no way replaces a metered evaluation o ull tone

color coordinates and the tone value increase or using an automatic color

control that may be on hand.

Why Gray Balance?

Standard process oset printing states that the correct dot gain or each

dierent printing ink is one o the most important preconditions or bal-

ancing printing and proo. It has also been determined that the dierence

between the colors is not to be too great (key word: spread), or a devia-

tion, or instance in the gray balance, may occur.

Usually the dot gain o each single process color is measured to veriy this

stipulation. Even beore a measurement is made, a color shit (e.g. a red

cast) in the chromatic gray patch when compared to the true gray patchcan be detected by simply inspecting it with the naked eye. Fundamen-

tally, it is very useul to make an assessment based on screened mixed

colors (in this case the chromatic gray patch), since most images consist

o those tertiary colors. Print control elements that contain only screened

primary color values (no mixed colors) are not suitable or this type o ini-

tial evaluation.

How Gray is Gray? or Which Gray Balance is the Right One?

One approach in dening the most suitable chromatic gray patches

involves establishing exactly those CMY color value combinations rom

out o respective color characterization data that match comparable val-

ues o pure black (true gray), and/or that arrive at exactly the same

CIELAB color values when metering the color.

The chromatic gray patches on the ECI/bvdm Gray Control Strip were

determined using this method. These correspond with the denition or

chromatic gray in compliance with the international press process stan-

dard ISO 12647-2: A colour having the same a* and b* CIELAB values as

a hal-tone tint o similar L* value printed with black ink..

Respective characterization data or all printing conditions may be taken

rom the CIELAB values or black. Characterization data are determined

by means o test targets (e.g. ECI2002 test table) that were printed on

specic papers under controlled conditions. These data also serve as a

basis or the creation o ICC proles, which may be applied or data prep-

aration and proong.

Table 1 illustrates the CIELAB color coordinates and CMYK color values

o the three chromatic gray (CMY 70, CMY 50, CMY 30) and true gray (K

70, K50, K 30) patches or standardized oset printing on coated paper

ECI / bvdm Gray Control Strip Explanation 5

In printing, each chromatic gray and true gray pair look the same to the

human eye and ideally the color measurements show the CIELAB color

values rom the characterizations le o the respective printing condition

(here: FOGRA39).

It is also important to make sure that the respective ECI/bvdm Gray Con-

trol Strip is applied according to the type o paper used, since dierent

CIELAB values o the black patches and dierent CMY values result

depending on the printing process and printing condition.

Denitions o the ECI/bvdm Gray Control Strip gray patches or oset

printing are each based on the Fogra characterization data or standard-

ized oset printing in compliance with ISO 12647-2. The ECI produces

ICC proles by means o these characterization data, which can be down-loaded rom the ECI website. They also constitute a part o the Altona

Test Suite Application Kit.

Fogra published new characterization data sets in June 2009: FOGRA45

or heatset web oset printing on improved LWC paper (light weight coat-

ing), FOGRA46 or heatset web oset printing on standard LWC paper

and or oset printing on uncoated white paper (FOGRA47). In January

2012 another characterization data set or web oset printing on INP

paper (improved news print) was added (FOGRA48).

A list o current versions and their classication according to paper type

can be seen in Table 2 on page 14.

ECI / bvdm Gray Control Strip Explanation6

Is Process Control of Other Printing Parameters Still Necessary?

The ECI/bvdm Gray Control Strip serves as an early warning system or

quick test. When a visual balance o true gray and chromatic gray on

the press is impossible to arrive at the conventional way, such as by a

change in the inking, this is an indication that some basic printing pro-

cess parameters need adjustment. As a rule, deviations may be corrected

by changing infuencing actors (i.e.: another ink, adjustment o CtP

curves). In order to locate and remedy the ault, it is required to review

the dot gain and ull tone color coordinates o the inks and make an

assessment o additional areas (e.g. slur / doubling), which are typically

included in machine control bars. The ECI/bvdm Gray Control Strip is

thereore not a substitute or printing control elements, but rather a sup-

plement to these.

Gray Balance An ECI or bvdm Invention?

No! Gray balance is a known issue in the printing industry since decades.

Fogra covered the topic in many studies the rst was issued in the year

1953. In act in printing the control o the gray balance has been in prac-

tice or many years, or example it is utilized in the Ugra/Fogra Minitar-

get (www.ugra.ch and www.ogra.org) and the density-based color con-

trol systems rom System Brunner (www.systembrunner.ch). Simple

chromatic gray patches are still in common use in Scandinavian newspa-

pers.

2.1 ECI/bvdm Gray Control Strip Versions

The ECI/bvdm Gray Control Strip is available in three dierent layouts.

Depending on intended purpose and available space they can either be

applied singularly or in combination.

The Basic S Version

The ECI/bvdm Gray Control Strip S version consists o three true gray /

chromatic gray pairs. The true gray patches are arranged in 70%, 50%

and 30% tone values o the black ink. The tone values or cyan, magenta

and yellow in the respective chromatic gray patches were determined

rom absolute colorimetric color conversions o CIELAB values (o the

respective black ink value).

ECI/bvdm Gray Control Strip (S) FOGRA39 v2

Illustration 1: The Basic ECI /bvdm Gray Control Strip S Version

Two items are to be noted. Firstly, the CIELAB value o the true gray

patches originate rom the corresponding characterizations le. Sec-

ondly, when determining the chromatic gray patches the black genera-

tion setting was none (without black ink).

The control element is 36 x 8 mm. Each patch is 6 x 6 mm. The identica-

tion line o the wedge allows you to veriy the utilized printing conditions.

In this respect it is recommended to show the Identication line on the

printing orme.

The Expanded Versions L, M and M i1

The ECI/bvdm Gray Control Strip versions L and M are based on the

basic S version and contain additional patches or the measurement o

other process parameters.

Illustration 2: Expanded versions L and M with their density values

above each patch, identication lines below and an abbreviated version

on the left side of the wedge.

Layout L

The L layout is 291 mm wide and has a height o 10 mm, whereas each

patch (with exception o the last patch) is 5.5 mm wide. When necessary,

patch density values and the identication line below may be cut o so

that its height may be reduced to 6 mm.

This layout consists o 51 control patches in all, which may be grouped as

ollows:

Start and end patch, required or positioning hand-held scanning

devices in ront o the rst measurable patch and or their phase out

ater the last patch.

Paper-white patch used as a reerence value or densitometers and to

determine the paper color coordinate.

Three gray balance patch pairs, consisting each o one chromatic gray

and one true gray patch or visual gray balance control. The true gray

patches are laid out in the tone values o 70%, 50% and 30%. The chro-

matic gray patches are created rom out o the primary colors cyan,

magenta and yellow so that each printing condition indicated in the ECI/

bvdm Gray Control Strip identication line can ideally be visually

matched to the true gray patches.

Solid color overprint patches (trapping patches), or the visual and

technical evaluation o secondary colors (M + Y, C + Y, C + M), also or

the tertiary color black (C + M + Y). This allows the detection o ink trap-

ping problems.

Haltone step wedges in the our primary colors: black, yellow,

magenta and cyan. Each haltone step wedge contains the tone values

rom 10% to 100% in 10% increments. It serves or the visual (by way o

inking standards) and technical control o solid color inking and to

determine characteristic curves o printing.

Since it is oten very hard to distinguish between neighboring control

patches, small white or solid-tone guide lines that border each patch and

that have no aect on the automatic measurement o scanning devices

were added to aid the positioning o the sensing head.

Printing Conditions

The identication line below the patches contains the name o the control

wedge and the layout version (L). Following that are the printing condi-

tions, a reerence to the respective characterization le standard and the

gray condition in compliance with ISO 12647-2. The Internet addresses o

the project partners are also listed including those addresses where the

ECI/bvdm Gray Control Strip may be downloaded. Because the large ver-

sion may be shortened to save space you will nd at the let o the end

patch another three short lines with the abbreviated names and the re-

erence name o the layout version, the wedge version (v1) and the char-

acterization le name This inormation allows the easy identication o

each wedge.

Layout MLayout M at a width o 197.5 mm is the abbreviated version o Layout

L. This version should only be applied when there is not enough avail-

able space on the paper ormat or the application o version L. This

can be the case or instance when short grain pages are to be processed

in A4 ormat.

O course the 10 mm height o layout M may also be reduced to 6 mm

by cutting o the patch density values on the top and the identication

line underneath. The width o each control patch is 6 mm. Layout M

also diers rom Layout L only by the number o the primary color hal-

tone steps, where instead o 10% increments, 20% increments rom 20%

to 100% tone values have been indicated.

Layout M i1

Between the patches marked Start and Stop the layout M i1 con-

tains patches or the ast measurement o CIELAB values and tone value

increase curves with scanning devices. Six gray balance patches or the

visual assessment have been added to the lower end o the control strip.

Illustration 4: ECI/bvdm Gray Control Strip (M i1)

Layout tvi 10

The purpose o this control strip is the assessment o production prints

with regard to the specications dened by the standard ISO 12647-2.

For that reason the strip contains solid-tone and overprint patches as

well as haltone steps in 10% increments. The ECI/bvdm tvi 10 can be

used or all printing conditions as it does not contain graybalance

patches. The color sequence o the control patches is optimized or ast

measurments with scanning devices.

Important Note Regarding Measurement with Scanning Devices

The space or control strips on printing sheets is very limited. For that

reason the control patches o the layouts M i1 and tvi 10 are smaller

than specied by the manuacturer X-Rite or the manual measurement

in scan mode using the ruler. Devices marked Rev A at the bottom side

are not suited or the measurement o these strips in scan mode. Using

i1Pro devices marked Rev B, C or D, in some cases errors in scan

mode measurements may occure in particular on uncoated paper types

with an uneven surace or coarse screening. All revisions (Rev A-D) will

work properly i mounted on the iO scanning table. In order to achieve

reliable measurement results it is recommended to measure the same

control strip in the modes strip and patch and to compare the two

results. In the case o signicant dierences choose the reliable patch

mode and do not use the ruler.

3 Implementation of the ECI/bvdm Gray ControlStrip

Which ECI/bvdm Gray Control Strip Version Should I Use?

In order to make the right selection or the correct wedge to use, you have

to consider the printing conditions (see also Table 2 on page 14). Aside

rom this, there are three dierent layout versions available per printing

condition. This allows you to choose the most suitable version according

to the amount o space available.

Example: A matt-coated paper (paper type 2) is intended or the nal

printed product. The matching Fogra characterization data is identied

as FOGRA39. I there is enough room available on the paper, the L or

M expanded version should be utilized. This will allow a visual check o

the gray patches as well as a technical measurement o the characteristic

printing curves. In this case use the ECI_GrayConL_FOGRA39.pd

wedge. I there is only very little available space, the basic S version

identied as ECI_GrayConS_FOGRA39.pd should be used. The basic

S version is key or the visual control o a press run.

How is the ECI /bvdm Gray Control Strip Positioned?

All the dierent versions o the ECI/bvdm Gray Control Strip are available

as PDF les. Choose the version that best suits the printing conditions and

position the ECI/bvdm Gray Control Strip or instance in your imposition

program as a supplement to your usual control aids. In work environ-

ments that do not allow PDF les, the EPS version o the wedge, or exam-

ple ECI_GrayConL_FOGRA39.eps, may be applied. Make sure that the

printing condition in the identication line that this wedge represents is

still discernable.

ECI / bvdm Gray Control Strip Application12

What Can be Done when K-Gray and CMY-Gray Patches do not Match?

In principle, the standardized oset printing process in compliance with

ISO 12647-2 and/or ProzessStandard Osetdruck (bvdm 2001, 2003)

guidelines is to be instituted. Target values and tolerances are itemized in

the MedienStandard Druck 2004 (download o current version at www.

bvdm.org).

When however the chromatic gray and true gray patches do not corre-

spond, try adjusting the inking and damping control o one or more o the

process colors to arrive at a good match.

Example: a) When the chromatic gray patch has a red cast when com-

pared to the true gray patch, decrease the magenta and yellow inking or

increase cyan.

b) When the chromatic gray patch is too light when compared to the truegray patch, increase the CMY primary inks or reduce true gray.

It is to be noted that the gray balance patches only illustrate a bias. In

order to nd out whether the primary color inking is to be reduced or

increased you must make an additional assessment o other control bars,

or example check the haltone wedge o the L or M version o the

ECI/bvdm Gray Control Strip.

In some circumstances deviations arise that do not allow themselves to be

corrected by adjusting the inking. Let us take or example the ollowing

case: The 50% patch is acceptable, but the 30% is not chromatic. The

characteristic printing curve o the entire tonal gradation is not balanced.

Initially you have to rule out any printing aults (or example slur / dou-

bling, gradual ading, etc,).

Then it is absolutely essential that a characteristic printing curve with a

sucient increase in tone value is created throughout (or example by

means o the expanded ECI/bvdm Gray Control Strip L version). A cal-

culated correction o the CtP system may become necessary as a result o

the ndings.

It should also be noted that there are a multitude o possible causes or

printing problems, or instance in connection with the materials being

used (paper, ink, blanket, additives, etc.). The bvdm ProzessStandard O-

setdruck extensively describes possible causes and gives trouble-shooting

instructions. The Altona Test Suite Application Kit documentation

describes pre-tests to determine the most optimal inking and the correct

tone value increase.

ECI / bvdm Gray Control Strip Remarks 13

Gray Balance Remarks

It is well known that with process inks in oset printing, inking and

damping fuctuations show up more distinctly in chromatic gray image

areas than in colored image areas. This is why gray balance patches in

color control bars have been instrumental in the indication o printing

process disorders. Gray balance control should be carried out allowing

or the ollowing constraints.

On the one hand it depends on the prevailing printing conditions, or

instance the type o paper or the screening which tone value combination

o primary colors (cyan, magenta, yellow and black) result in an actual

chromatic gray in the print. Most o the control aids available up until

now (or example the Fogra control strips) have only one single version othe gray balance scale. In conventional lm / plate making, managing a

large number o control strips coordinated to all the dierent printing

conditions would have been extremely inconvenient and would probably

have presented a potential source o trouble. Still, gray balance devia-

tions in the print run can be well detected with the aorementioned con-

trol aids. By comparing the gray balance patches on the o.k. print and

print run sample, fuctuations can be easily detected despite the inaccu-

racy o chromatic gray balance patches. Today thanks to automated

workfows it is easy to display control aids on ull-page lms or printing

plates that match the intended printing conditions.

On the other hand, the gray balance is dependant on printing parameters

that are infuenced by at least these our actors: the dot gain, the solid

color inking o the primary colors, overprinting and paper color. A gray

balance control alone can thereore not give any inormation about any

potential cause or errors and in itsel does not allow an assessment or

recommendations at the press. Now as ever screened patches o the pri-

mary colors, solid color and solid color overprint patches are required in

color control bars. This also applies to automated control systems that

unction according to the gray balance control principle.

The gray balance o the o.k. sheet are reerence or the process control o

the entire print run even i the respective chromatic gray patches are

not perectly neutral.

A color cast in the chromatic gray patches o the ECI/bvdm Gray Control

Strip not neccessarily indicates the same color cast in gray tones o

images. In particular dark image areas contain a signicant amount o

black ink. This minimizes the color cast caused by the chromatic inks

cyan, magenta and yellow.

Upon request ECI will create special versions o the ECI/bvdm Gray Con-

trol Strip or publishers o characterization data and proles available on

the ECI website.

As an exception the opportunity is available to create your own versions

corresponding to special printing conditions. For this purpose ECI and

ments along with a manual are located in the older Custom which is a

part o the download package.

Characteristics of the new Version 2

In version 2 o the ECI/bvdm Gray Control Strip, two bugs have been

xed, which may occure when creating PDF les or when printing docu-

ments containing the previous version o the GrayCon: moved other

page content, moved characters in the ino text on the control strip, such

as the numbers above the patches.

The ECI, bvdm and Fogra recommend the immediate use o version 2 in

order to avoid these problems. The adjustments have no impact on the

measurement o the control strips as neither the layout nor the color

values have been changed. The version is indicated by v2 in the le

name and on the control strip.
