Brilliant colors true to the original on a premium surface – that ̓s what distinguishes a high-quality print product. Many elements in prepress and printing impact on a product ̓s color fidelity. The various input and output units in a print shop ̓s production process, consumables and other factors can cause deviations in color. A consistently employed color management system eliminates this problem.

In this series of blog tips we ̓ll show you the most common sources of error and give you tips on color management. We ̓re pleased to have caught your interest.

Step 1: Choose Consumables

Consumables have a very large influence on the print result. Deciding on set materials creates a basis and defines the boundaries. Changing consumables produces new results, which may necessitate recalibration. Thorough planning is, therefore, required. Examples of consumables include:

 Printing stocks

 Inks

 Blankets and underlays

 Dampening solution (additional amount + IPA)

 Printing plates and development chemicals

 Proofing paper and ink

Grades of paper

The ISO 12647-2 standard defines the specifications for 5 different grades

of paper.

Paper Grade Description

1. gloss coated, woodfree, 115 gsm

2. matt coated, woodfree, 115gsm

3. gloss coated, LWC*, 70 gsm

4. uncoated, white, 115 gsm

5. uncoated, slightly yellowish, 115 gsm

A multitude of possibilities

Different prepress and print processes as well as different materials all produce different results! It is, therefore, essential to coordinate all processes and limit the options for coloring.
