I would like to print a good red on my HP Latex 315 that I have been using for the past 2 years.
Solid red on a white substrate Metamark MDP-H
Please consider that I use this HP Latex 315 only for printing italian standard safety signs.
Solid black on yellow substrate; solid red, green or blue on white substrate.
When red is involved I just use the Mimaki wich is getting old though
I never been able to achieve a good red, a deep orange on the best days with the best setting:
20p - 120 density
Today I wanted to get the reddest red I can get so:
I have already tried to change the CMYK of my red, the only good alternative was 0-95-100-0. Adding Cyan or Black took away brightness from the red.
So i wanted to ask: Can you print a Red RAL3020 on your HP Latex? Or any good deep red
Can the Latex 315 achieve a good red?
If that's a yes I guess that the three possible culprits for my problems may be:
1) ICC - I can't create my own ICC (no spectrophotometer, no options from HP Latex 315). I tried the factory preset for Metamark MDP-H but it took away brightness from my colors. I just print without color correction. I only use the linearization of the preset when I want to change the density/passages during the print (standard usally 10p - 110%)
2) faulty printhead - maybe the magenta doesn't get pushed out correctly? The printhead test looks perfect though
3) dumbness of the operator - Am I missing something?
Thank you for any help!
If you need to create an ICC, you have to use an external spectrophotometer in order to have a Red RAL3020.
In this what I can recommend is performing a nozzle check, and if some PHs are not performing correctly I recommend cleaning them.
