Accurate colour reproduction of electronic files can be a difficult process. If you choose ink colour electronically, two major factors may make it difficult to get an exact colour match on a colour printer or a printing press:
• First, due to calibration problems with computer monitors, the colours you see on your screen may not match the colours produced on a colour printer or a printing press.
• Second, computers display colour by using the additive primary colours of red (R), green (G) and blue (B), whereas the printing press reproduces colour by laying down ink films of the three subtractive primary colours of cyan (C), yellow (Y) and magenta (M) plus black (K).
Working within these constraints, we always take great care to achieve the closest possible colour match.
However, if an exact colour match is critical, we urge you at the outset to consult Computerforms. Together, we will discuss the best possible method for producing the job, according to your specific requirements. After all, we want you to be completely satisfied with the finished product.
As a guide the most common practice in the European printing community is to stick with the "Europe prepress defaults", which give the CMYK space of European coated V2. A good idea is to run a monitor calibration utility like Adobe gamma monitor. We would, however, recommend the use of a Pantone® Colour swatch rather than relying on screen colours.
Irrespective of design, it is important that we are aware of which colour-match method applies to your existing forms. Where possible, it would also be very helpful if you could embed the colour profile into the file.
