Alongside digitalization of the original, the proofing phase is extremely important.
It is here that the eye and expertise of the color lithographer is absolutely essential. His knowledge and skill ensures that the color of the facsimile is as close as possible to that of the original.
There may be pigments in the original which fall outside the photographic spectrum, or which bend due to the refraction of light and cannot be properly digitally recorded. The color lithographer finds solutions to this through applying various color corrections and making numerous color proofs.
In many cases, digital masks are created in order to save colors, whereby accurate corrections in color can be made.
The color lithographer creates the master file
Because the color lithographer works with the original, he can correct a color directly to that of the original. The knowledge of the conventional lithographer is applied digitally in this modern age, and is still of utmost value.
The proofs are produced on the print paper and, once it has the approval of the color lithographer, the master file is ready to start printing.
