Confirm the plate technology
Record the full plate name, CtP or CtCP technology and the manufacturer’s recommendations. Do not assume compatibility from a similar product description alone.
Collect processor parameters
Check temperature, speed, contact time, replenishment, consumption and change intervals, as well as brushes and rinsing.
Choose the product form
A ready-to-use product reduces mixing risk. A concentrate may improve logistics but requires accurate dosing and suitable water.
Run a controlled trial
Change one parameter at a time. Record settings and evaluate background cleanliness, detail, coating resistance and press performance.
Define a control standard
Set measurement frequency, bath replacement criteria and responsibility after implementation.
Check exposure before changing chemistry
Unstable exposure can look like a developer issue. Verify platesetter calibration, optics, control strips and processor condition before comparing developers.
Use a bath-control record
Record temperature, conductivity, plate count, replenishment, replacement date and visual results. Trends are more useful than isolated measurements.
Evaluate the plate on press
A clean plate after processing is not enough. Check ink acceptance, non-image cleanliness, tonal stability and plate durability under a real production run.
