Print colours and printing process

Colour System

Unless otherwise stipulated in the product description, we print using the CMYK colour space and the standard four-colour process.

Printing Processes

Offset Printing

Offset print is an indirect printing technique in which the inked image is transferred from a plate to a rubber blanket and from there onto the paper. It takes advantage of the lithographic process, which is based on the repulsion of oil and water: a flat (planographic) image carrier on which the image to be printed obtains oil-containing ink from rollers, while the non-printing areas are coated with a water-based film (called fountain solution) which keeps them free of ink. For four-colour printing, this process is repeated in multiple printing units or towers, each of which prints a different colour (cyan, magenta, yellow and black).

Sheet-fed offset presses print one sheet at a time. We print newspapers on web presses, which print on a continuous web of paper fed from a reel.

Digital Printing

In this printing process, the image to be printed practically goes straight from a computer to the paper. Digital printing merges the technology of a colour printer with the mechanics of a press. It is therefore similar to a laser printer, in which electrostatically charged portions of a drum attract toner particles and transfer them to a sheet of paper, which is then heated to permanently fuse the text and/or images.

Because of this, digitally printed documents cannot be passed through a laser printer afterwards, as this would cause the printing to peel off.

Colour Variations

Although we use state-of-the-art presses, there is always the possibility that printed colours will vary slightly. This can be due to many factors:

• The properties of different papers, e.g. their whiteness
• The grain of the paper
• Whether matt or glossy paper is used
• Climatic conditions in the pressroom, such as temperature and humidity

Unfortunately, therefore, we cannot guarantee that the results will perfectly match your artwork. However, provided that you comply with our requirements when creating it, you can look forward to satisfactory colours in nearly all cases.
