This has happened a number of times now. PDF sent with raster elements that does not have pure white beyond the edges. For yards signs I don't worry about but for POS stuff it looks crapy. Not real practical to try to add a 1% raster over the whole job so that OC prints over the whole job, or not crazy about turning off the OC and losing that protection. I don't see any setting in Caldera to flood the OC and have never heard that is possible with any RIP.

How are people handling this problem.

Have you tried with transparent profile? It has algorithm to help with that.

WTF why and how did they do that with transparent SAV media preset and not the SAV preset? Seems to work without that OC beyond the edges of raster objects. Looks like I have a lot more profiles to build but why do that on a preset that doesn't support calibration.

I would look at your artwork - our 700W pretty much prints the OC over the image, not with that huge blocky crap.... Though I have seen it. I believe when we sent a very low resolution background with higher resolution elements on top (like your type on top of graphic.) I am not entirely sure how the rip determines the area to put the OC, but I have noticed that if I have a really wonky image that obviously has many different resolution layers, we can get very blocky OC on the image. In this case I will force everything to be flattened to the same higher resolution (still looks the same, but you may be printing the 30dpi blocks at 600dpi - the pixelation is now just part of the regular artwork...)

If anyone has a better answer for this pixelation of OC on the latex, please chyme in...

It is just amazing the difference between the preset from Transparent SAV and regular SAV. What in the world would account for that? Can't see were the RIP setting would make any difference between those two presets? In fact I ran the same job only changing the media and it associated ICC profile. The Transparent SAV ICC profile was downloaded from the printer and the regular SAV was one I created. I will have to investigate if that makes any difference.

The difference is hidden in the printer, you can't do anything about it.
Really this issue is with your image and that's also why HP did it this way.

Removing the OC halo offers less protection on that edge area. However it can be extremely visible on colored and transparent medias even with good vector files. So it's usually preferred to have it fixed.

If you clone it, can you still not calibrate it?

Nope. If you start a new transparent SAV media preset you can't calibrate that either. Probably use RIP linearization for the ability to re-linearize but with Caldera you can't force 100% of each color. I have to edit it later and I suppose re-linearization would remove that forcing me to edit the re-linearization.

I am also looking at what if would take to flood the OC. It would be nice if there was a RIP option to do that.
