For consistence Printing DG,plate controls is obligatory

Every week produce a test plate which has a “plate scale” job on it.

Plate Scale

Measurements are done and recorded by a plate measurement device. Then the program calculates the dot gain of the plate

Plate Quality Report

%2, %98 and % 50 tone values are measured with plate densitometer by the prepress man to understand if there is an abnormality or not. If the values are seem to be changed, he produce a test plate for exact measurement and calibration

Daily Plate Checking

A tone scale stays on the bended side of the plates is checked daily.Plate is taken before P&B machine for measurement.

Customers complains mostly :from the “startup “ newspapers or “restart - following a stop ” newspapers.

Because mechanically they are the worst.

salable , low quality, not salable,


C Consumabels Reporting a) are being used (Current)

Ex: Newsprint Evaluation Reportb) Test metarials

Target is;To prepare a list to our purchasing department.Show preferred and not preferred

So we ask: not to bought unwanted, instead, the preferred if possible much
