Printing HP Bar code Black

Is it possible to print the deep black colour found in the HP barcode? This seems to be the richest and deepest version of black my printer produces. I have not been able to print this colour. The black used in the print attached is C: 60 M: 40 Y:40 K:100

#1 Hi Christian

For these color management problems, we must take into account the following parameters.

-Control which ICC profiles are being applied to the raster. -Check the color calibration factors at the Rip software.

In your case , it seems that the ink levels are not sufficient to achieve the "deep black" you are looking for.

We recommend increasing the ink levels of the C, M and Y inks by at least 70%.

To avoid IQ problems related by the increased ink we recommend you to increase the number of passes of your job.

I hope had helps with your issue.

Best regards
