Silver printing pinkish in some spots

So I know about profiles causing colors shades to be off but what would be causing on certain spots to have a magenta tint to them? Say I print a sheet full of the same decals that are silver, some in the middle and edge are more pink than others. While some look just fine. Using Flexi but this has never been a problem with this color in the past. And since it is random on the page it seems more of a machine issue. Thoughts?

Have you had any head strikes on this job or the previous one? I've noticed that after a head strike, sometimes we'll get a bleed-over effect between the colors. Most commonly for me, it's been the black bleeding into the other colors. Sounds like magenta could be mixing with your metallic perhaps. Running a powerful cleaning usually clears it up.

The machine is non-metallic. Just a simple CMYK SP-300V. So the silver is simulated using inks. Replaced cap tops, wipers. One head was replaced a few months ago. Alignment was done. But is still seems to be happening. Below is a zoomed in picture of the issue. It's almost like some weird digital pattern in those areas instead of being more of a solid color like the rest of the print. Only seems to really be noticeable on silver.

I know this is an old thread but still can't get silvers and grays to print correctly. Pink keeps showing up in them. Here is a silver zoomed in so you an see the crazy pattern it does to create this shade. It seems to happen most noticeable with silvers and grays. Other colors print fairly consistent. The attached image shows a stripe that is about 2 inches wide so you can tell this is quite obvious when viewing up close. Should grays look like this?

Hey IsItFasst,

Color contamination in prints can be caused by a variety of factors, color management settings being the most common. Since Roland does not troubleshoot in user forums, if you want to continue this conversation, it's strongly recommended that you submit and official Roland support request online here: Product Support Form | Roland
