3M 8518 Laminate causing greenish color shift

    I am using a Roland SolJet Pro III XC-540 (ecosol) printer, and cold laminating printed films and discovering that my prints are color shifting after being laminated.

    We print most often with 3M IJ180C & laminate with 3M 8518. The laminate appears to be adding a 'greenish' tint to EVERYTHING!?

    For instance...print a nice gray color, laminate it & it will take on a greenish-gray look. Print a nice yellow, laminate it & it looks like a 'dirty' cat-crap yellow.

    It changes some colors so significantly that we need to adjust the output to achieve the correct color after lamination.

    Help? Advice?

    Some laminates are known to have a blueish tint to them and will cause the color shift you are seeing.

    Try another brand or use an optically clear laminate.

    Doesn't 3M already claim that the 8518 IS optically clear!?

    I have had good luck with Avery products, just a thought. I hear oracal doesn't suffer the color shift either.

    I got fed up with the green hue on the 3M laminates, optically clear isn't the right option either it is expensive and doesn't conform the way 8518/19/20 do. It is meant for window perf.

    I know a rep of a supplier who says that 8518 is more optically clear than Oracals 290 optically clear laminate. I have not verified this but if 8518 is shifting the color on your print then its not optically clear (or at least not to the standards that we want).

    We use a lot of LG polymeric vinyl and lam and the lam will give a horrendous green cast over greys.
    We created a "laminated" profile which solved the problem pretty much.

    If you have the ability that's the way to go.

    You'll see it on light greens, greys, and flesh tones. Not much you can do to avoid it

    Create two ICC profiles for the media, one without and the other with the laminate applied. Neutral (grays) and near neutrals (pastels etc) are the most likely to be affected by the color cast of the laminate. Measuring the ICC chart (only) through the laminate will correct for the cast that the laminate imparts.

    This is the only way we create our profiles. You have to scan the swatches in from the final product for it to be accurate. Scanning it in unlaminated gives you a profile for unlaminated. Laminated will almost always be different. And yeah.... 3M does give a greenish tint more than many others. We will use it if specified but for the most part we reccomend and use Oracal 290GF (optically clear cast).
