Hello,

I hope you guys can help me. I recently made an ad in adobe illustrator
which has a greyscale image with an orange to transparent gradient on
top made by creating an opacity mask. Well on the screen it looks fine
and so I sent it to the comercial printer. However when the comercial
printer gave us the proof it shows a sort of lighter hue band in the
area where the orange gradient ends and meets with the grey image
below. In other words, instead of the gradient blending smoothly with
the grey image below (as it shows on screen!) there is like a lighter
strip that just almost ends abrouptly and looks bad where the gradient
ends.

This same thing had happened to me with almost the same ad in the same
place when I took it to Kinkos to print. However this time the gradient
and the greyscale image were one rasterized bitmap image exported from
photoshop. The guy in kinkos was telling me that it is a problem that
appears because the image has an area of just k and sudddenly it goes
to color and it not always goes smoothly. Well I told him that in my
printer at my office that didn't come up, but he told me again about
the k to color problem which was odd to me because this time it was
just one image like a photo so I don't see how that could be my
problem. Anyways I suggested he try printing it from another printer
there at kinkos and he did and this time it came out without any
problems. So that solved it that time.

But my current case is that the proof from the comercial printing is
showing this band again, so my question to you all is this: Is this a
problem that the Comercial printer should solve or is there something I
can do to correct this in the illustrator file?

Any help/suggestions will be really appreciated.

Thanks,

Aluxe
