Need Help Flexi Ripping: Dark Prints

[DJBread]

Hello,

We are experiencing a weird problem when printing a job on our Mimaki JV330. Sometimes a job's color was looking great when we print a sample; however, a couple days after we ripped the job, we start printing the full customer order from said pre-ripped job and the color is incredibly darker than the sample. If we rip it again, the color is restored to match the sample.

I don't know if this is a Flexi problem or JV330 problem, but has anyone else ran into this? It is not stopping production, but it is time consuming to rip the file again because the files are quite large. Any help or insight is appreciated.

Thanks in advance!

Flexi Production Build: 4835
Printer: Mimaki JV330-160

It sounds like a possible Flexi bug. When you print a sample, it only RIPs that part of the file. So when you tell it to print the whole file, it's not fully RIPed so it prints like you're not using color correction at all which pretty much always prints really dark. You would think Flexi would either prompt you that you need to reRIP the file or just do it automatically but that might just be something they missed in programing. If I were testing my theory out, I would print a sample that's close to the front edge of the print. Then print the full file without reRIPing and see if everything prints dark except for the sample area. If it does, that verifies that's exactly what's happening.

When we print samples, we actually tell Flexi to print a whole sheet and then we cancel the job 1.5' into the print. We do this because we found out that even cropping our images effects the color correction between the cropped and full image jobs.

The weird thing with this is that the rip should be set up to print a whole sheet, but it still avoids color correction or puts down too much ink before we re-rip it.
