I recently purchased a new i1Pro2 and started making some profiles for my two printers. I am trying out two Red River papers Ultra Pro Satin and Palo Dura Satin as inexpensive proofing papers to proof prints before printing on the expensive cotton rag papers.

I let the targets dry down for a minimum of 24 hours before making the measurements. Even so I notice that the target print is slightly warped and tends to lift up off the reading table in the center. Apparently this is enough so that the edge of the nosecone furthest from the ruler will scrape away thin lines of ink from the paper surface.

These are both relative thin papers, 10mil, I believe and it seems that the amount of ink being laid down is causing the paper to distort. I do not have this problem with any of the thicker cotton based papers.

I opened a support ticket with X-Rite and they have not said one way or another if this is a problem.

I do recall that the previous i1Pro ruler had a slot that held the paper flat on both sides of the row being read. So I even tried placing a ruler on the other side. This helped but does not eliminate the problem.

I suppose I could file down the corner edge of the nosecone and see it that helps but I wanted to see if this has happened to any one else first.

tks, louie

Flip the paper and read from bottom up.

Flip the paper and read from bottom up.

No need to flip the paper, the GUI isn't going to change.
What you (what the OP) can do is measure from the bottom Up-wards but after each row, the software will attempt to move the next row down from the top, no way around that direction! So the user must manually move the outlined area to be measured to the next upward row from the last. Easier to show than speak of: bottom (last) row measured, UI (outline) moves to top. Manually move it to the seconds to last row, measure and continue upwards.

6 of one, half doz of other.

But alternative choices always appreciated.

Thanks, Andrew

Edit...rereading your method...am I correct that you would now, for each new line, need to not only move the physical line, but also move the line on the screen?  If so, my method is slightly easier as you do not need to futz with the line on screen...moves automatically

All explained in post #3.
What product are you using to measure the target?

Not using now of course, but, from memory....

Upright target, start at top
Align bar at 1st line, read (back and forth), UI moves down, you move bar down

Upright target, start read at bottom
Align bar on last line, move UI bar to last, read, UI moves to top, you move bar up one, you move UI down to next to last line....then, you move bar up, UI bar now on last line, you move up one, etc.

upside down target, start at bottom (line #1)
UI is on line #1, bar is placed on line #1 (bottom of upside down page), read, UI moves to #2, you move bar up to line #2, read, etc.

He stated i1Pro2.  I assumed iProfiler.  What did you assume?

Try it, then tell us what you see.

I try not to assume.
You asked me to help you understand. Actually try turning the target upside down, even move the bar to the bottom and scan that last (now top) row. What happens to the bar?
There's a screen capture for you below!

No screen capture

I have often used the upside down case.  Have you tried it or are you working from memory....because I believe you usually use isis and haven’t played with a puck in years.

I don't work from memory. I tried this just today (twice actually) to produce the screen captures also produced today. Look at the date/time of the captures!
You and I can read from the bottom up, but the GUI doesn't care.

A massive assumption on your part! I build all kinds of profiles for clients that can't fit into an iSis. I don't play (with puke or otherwise).  ;D

Did you just test one page or a multi page target?  If you read line 20 of a multi page, it flips to page #2.  Your method works, but needs a lot of manual adjustment of UI and is prone to errors.  Turning page over works,...no problem.

So you like to make fun of spell checker (puke), even after it was corrected (puck)....so be it.  Ha, ha.

Man, you are the master of CWOBaT (colossal waste of bandwidth and time).
One page. Makes no difference; the behavior is the same.
What I made fun of is your assumptions about the instruments I use professionally and your memory.
Now maybe one of us can get back to helping the OP who probably ran away from this for good reason.

Only for posters who are prone to errors. That's been clearly illustrated.

Your habit of attacking others to try to win discussions has a tendency to turn them into arguments and is what is really dreary.

I tested reading line 20 (1-20) on a page and it flipped to page 2.  Do you agree that iProfiler does that.

While you can switch back to page 1 and then read line 19, move the UI line from 20 up to 18, read, move UI line from 19 up to 17, etc, it is a PITA.

Easier to flip page, read line 1, UI auto drops to line 2, etc.

Does you xRite software work different?

I had the problem on some papers using the I1Pro 2 table. Turned out to be a combination of things.

1. I was pressing down too much towards the front of the I1. Best to use a light touch towards the back of the device. You also get more even scanning though that's much less important than in the earlier I1Pro which didn't use quadrature to keep track of position. The quadrature resolves to .5 mm so the software always knows where the I1Pro 2 is.

2. I once tried scanning on a portable, plastic table. It didn't have an even surface. I quickly went to using the scanning table on a very flat marble countertop. Big reduction in print hits.

3. However, there was still the occasional I1 Pro contact and scraping. Wound up putting a single layer of Scotch invisible tape along the ruler surface the I1 registers against. Not the bottom. You don't want any tape anywhere touching the charts.  Then trim it to the ruler with a razor. It's a bit less than .001" thick and that, together with the above eliminated any problems.

I agree with flipping the Chart. It's easier and less error prone.

Works for me.

When I first started with the i1Pro2, I had some difficulty with it not being a smooth slide.  This maybe unique to me, but after much trial and error, I found a solution the works...for me, at least.

Instead of having the unit in front of me, sliding in the left to right direction, I turned the unit 90°, so it now slide close to far from me.  This allowed me to more easily apply uniform pressure with both hands, avoiding any binding or possible tilting of the “puck”. (Tilting, which might be some cause of the OP’s scratches)
