Xerox 700 Printing yellow

[sahagin]

Hi all,

i have a Xerox 700 with freeflow, and when i print a job usig 100% Y (only yellow) from CMYK, i can see from the preview on freeflow with the picker that it has Magenta like 5% and 95% yellow.

Resulting in a slight darker yellow, i can even see the magenta dots using a magnifying glass.

Is this normal??


thanks

Looks like you have some color management occuring at some stage in your workflow, which is normal by the way. I would start by checking what simulation profile you're using in your rip. Basically, what simulation profile does is tell your Xerox (through it's rip) to simulate the color look of a printing condition/specification (such as SWOP) on your paper output. To achieve that goal, the rip sometimes needs to desaturate the solid colors by limiting solid density and/or adding other ink blends to it. Hope it helps.

I'm using Corel X5, and i use the SWOP v2 color profile in it, on the Freeflow, i guess it uses, if i understand this correctly, on the Color Management, GRACOL 2006 CMYK.

However, ive tryed to change this to another one, or even use embedded profile, with the same results.

My problem with this is that i print a lot of business cards and the logo uses the 100% Y, and i have printed perfet yellow.

I dont know if i changed profiles or so, or if the machine is tricking me.

The question is, what color profile to use to achieve yellow 100%.

Tank you

Its not so much one specific profile, you can use any profile. Each profile is still going to see 100% yellow as 100% yellow, the issue arises when you start using different profiles. ex: You print to pdf using X profile. then the pdf is printed to the Xerox using Y profile.
Your RIP then converts X into Y, resulting in a slightly different colour space.

i print directly from Corel, and i tryed both options:

- Corel corrects colors using profile

- or Xerox

I dont see any diference between them.

try turning color management off in CorelDraw.

FreeFlow uses a profile to RIP the file to CMYK, whether or not it is CMYK already, and then uses another profile to RIP it to a destination profile that you have made.

You need to print it using pass-through color. Does your FreeFlow have a printer profile in the Advanced Settings tab? It may be called 700 CMYK or similar. Also change the destination to a similarly named setting. You probably have a queue for this already that you use for checking color or calibrations.

I would send it over as a PDF-X and turn on your PDF-X setting on the freeflow server under color management. That will by-pass the server's color management.
