Ink Density

[psbc2009]

Printing on oracal wrap material using manf. profile. Color and quality look good. My installers said ink is not heavy enough -getting whiteout over curves etc. My question is how do I increase the amount of ink being put down?? I have tried a couple of different profiles with similar results.
In profile settings "Passes is grayed out". Does more passes = more ink?
Any help wpuld be appreciated.

What material are you using?

 

[psbc2009]

Oracal 3951.

That's odd. If your getting whiting then it's simply being stretched too much. Oracal takes more ink then most all materials out there so saturation shouldn't be a problem.
Are you off gassing for 24-36 hours pre-lamination?
Are these your installers or do you outsource?

depending on what RIP software you are using, it's typically called "ink layers"

The white that the installers are seeing is because they are stretching around corners and forcing the graphics into place. I'm not sure if the graphics aren't allowing enough play in order to make the tight turns, or if the installers are just forcing the issue, trying to get it into a place it doesn't like, but stretching the vinyl that much is going to cause it to fail prematurely.

Prints are sitting at least 24hrs. pre lam, my installers. I am using Flexi 10.
So bascially using the correct profile with said media I should be good to go?? A friend of mine has a mimaki and he can adjust amount of ink being put down on the fly by changing a setting on the printer itself. Apologize if these are dumb questions

in flexi it is called ink layers, I'm almost 100% positive about that. The problem with that is, it will shift everything much darker, so it will require a rework of all the art if you are color sensitive.

pre lam

Pre-Mask or lamination?? You should be using 290 oragaurd on this.

You will almost always over stretch without actual lamination. Plus, you will fail fast anyhow.

using 290 - will look at ink layers tomorrow when i get to shop - thanks for all the replys

Ink density is controlled by the profile.
Matte medias typically will take more ink, so you might try a matte profile to get more ink.

This does sound like overstretching of the media by the installer, however.

I'm definetly onboard with the "over-stretching" theory.

Are your installers using torches? They should be, if not.

But we encountered a lot more "whiting out" or color loss with 3910 then we now do with the IJ380v3 product by 3M.

The 3M product seems to want to conform a bit more in my opinion.
