The problem
I received newly printed business cards and on some of them the logo color is very different compared to the others. I would like to understand what might have happened and what I need to check before having them reprinted
Cause and analysis
The file sent to print was in PDF format with CMYK color space, which is the correct standard for offset/digital printing. The color variation in the logo between different business cards could depend on production process factors (printer calibration, humidity, ink) rather than file errors
The color variation could also be caused by improper color conversion during the production workflow, or by a master file that was not correctly profiled before conversion to CMYK
It is necessary to verify the original PDF file to rule out that the problem stems from variations already present in the file itself (color separations, transparencies, incorrect blend modes, or inconsistent color application to the logo)
Solution proposed by GPX
1. The logo might have transparencies or blend mode effects (multiply, screen, etc.) that behave differently depending on the resolution or color separation rendering during printing. 2. If the logo contains gradients or composite colors (multiple overlapping CMYK channels), fluctuations in printer quality control or ink density cause noticeable variations. 3. The file might contain an embedded color space that was not interpreted consistently by the printer driver or the RIP (Raster Image Processor) at the print shop. 4. The print shop may not have used the correct ICC profile during printing, causing inconsistent color rendering. 5. Physical process variability: paper humidity, temperature, ink roller settings, or press calibration between one print run and another
