Xrite i1io scratching inks when reading in proof profile

[shorty83]

Hi, I am trying to set up a proof profile for some silver stock and am reading in the charts with the Xrite i1IO table. The charts were printed on silver stock using my EsponWT7900 printer. I let the charts dry over night and when I use the table to scan in the charts it scratches the inks off the material as it is reading them. Has anyone had this issue or have any insight on a solution? The only thing I can think of it to put a clear overlay over the chart but I am concerned it will not be an accurate reading with the overlay. Thanks in advance!

silver stock never drys properly without laminate, so wouldnt be a bad idea to profile it with laminate on.

Incredibly bad response but you did adjust for the paper type so the head isn't dragging on the substrate?

bad response? have you printed on that paper, it recommends a laminate, would be interested to see the profile it makes with a silver background as well.

I meant my response! Just it was a question that begged to be asked.

Thanks, but the printer won't print laminate so a clear overlay is the closest I can get :-/

I did adjust the head to be higher but the i1io is actually supposed to be touching the stock according to the manual for accurate color reading. But, I may just read it without it touching since it will probably give a better result than the overlay. Thanks!

After measuring, note some random colour samples in the measurement data.

Then compare the values to a spot read using the i1 hand held, just to see how much variation there is vs. the raised measurement height on the table.

Stephen, what would you agree to on for an acceptable dE tolerance, 1.0?

Which dE (that is always the burning question)? Whichever it is, hopefully much lower than 1!

Had the same problem years ago, the reading is usually made of the color and the scratches are made as the head moves on. Just can't re-read the patches. Try the profile and see.

Reading in patch mode will reduce the scratching. I don't think you're going to get good results leaving the head hanging above. If the head isn't touching the surface you change the geometry of the sensor, not to mention the falloff in the light intensity.

Thanks, I did the reading in patch mode and it worked much better!

Another option for the future is to take .5mil clear film/lamination (no adhesive) and just lay it over the sheet to be read in. We have done this on specialty stock in the past to prevent the scratching. The static holds the sheet down pretty well but we usually just taped the clear film on the edges. Readings with and without were always close enough for our purposes but we had very clear film. Some lamination tends to add yellow to readings. Hope it helps.

Now that you have readings in row and patch scanning modes, what is the difference in the readings?
