Colours are no longer just a visual effect. Today they are measurable, defined values. To get perfect printing results, Janoschka uses their extensive know-how to coordinate the interaction of up to seventy variables. These include the various makes of printing ink with their different solvents, pigments and properties, the range of substrates (aluminium, a variety of plastics, paper etc.); the printing tools with their screens, angles and gradations; all the way to the printing presses themselves, with their varying parameters, such as counter-pressure, speed etc.
“Colour management is the unique and reliable method for producing contract proofs out of these complex interactions for which there are hardly any industry standards,” according to Dirk Jauch, Technical Print Consultant, Janoschka Holding. “Everyone involved – from the manufacturers of print substrates, printing ink and doctor blades, all the way to us, the cylinder makers, of course, devote our entire know-how to this profiling process. Within a few hours, we can define a colour space that reflects all relevant parameters and further shortens the lead time for each new product.”
Janoschka’s professional colour management, which is continuously being tweaked, is where the company’s entire extensive prepress process know-how bears fruit. The reproduction is therefore not only based on the respective printing process, but is also tailored to the facilities of a specific printing plant. The prepress specialists then print suitable reference images, test charts and control elements on site using a test cylinder. This provides a snapshot of the individual printing conditions of a specific printing plant.
