v2012.216    03/05/12

Priority: Low

v2012.216 includes the following:

  • Process larger files: v2012.216 allows opening very large files: up to 1.5GB and beyond with some compressed formats under Win7 x64.
  • Canvas shrinkage compensation: Check the job properties tab for the new canvas shrinkage compensation feature.
  • Fix: Fixed a bug where the print properties button was not working on prints that have a mirror edge border.

Thanks Mike!

  I was intermittantly experiencing the bug also and was about to question why it was happening. hongu123 beat me to it. Thanks for the fix!

As far as the canvas shrinkage adjustment. Will it mostly be a matter of experimentation to get the setting right with individual products ,and then save it as a printer setup? Any guidlines as to where to begin to adjust?
Great feature BTW!!  Grin

Thanks,David

If it also does that on Vista x64 you could not have chosen a better day to bring this upgrade. Have to print 3.5 x 8 feet rainbow pieces on Wednesday. Compressed Tiffs too?

You could probably google it for the printer/paper you are using and find something but it really only takes one test print to figure it out.  Print something and measure the length.  If you print 36" in length and what comes out is actually 35.5 inches, then your shrinkage is 36/35.5 or 1.4%.

Mike,
My printer stretches every 20" of image to 20.2" of canvas. Just to make sure I understand this, 20.2/20 = 1.01. Thus I would input 1.01 into the shrinkage field and Qimage will vertically scale the images down so that they print to 20"?

Canvas typically shrinks.  Are you saying yours expands?

My bad. I meant to say that my printer/canvas shrinks every 20.2" of image to 20" of canvas. Just to make sure I understand this, 20.2/20 = 1.01. Thus I would input 1.01 into the shrinkage field and Qimage will vertically scale the images UP so that a 20" image would print 20"?

Mike,

No, not correct.

The proper calculation for shrinkage percentage would be

100*((20.2 -20)/20) = 10%

Well, if I'm going to be a smarty pants, I guess I should try to get it right!!!

I meant 1% and not 10%

I'll get it right yet.

After due consideration and consultation at the highest levels:

The percent change is the change from the intended amount divided by the intended amount times 100.

Therefore the correct answer should be

100*((20.2 - 20)/20.2) = 0.99%

since the intended amount was 20.2 and not 20.

Well, since I'm having a conversation with myself, I will continue.

I finally looked at the "Canvas shrinkage compensation" input for Qimage Ultimate.  It says "stretch the length by this amount".  If this is really what is wanted, it seems to me that what we need to be calculating is the percentage to stretch and not the resultant percentage shrinkage from the desired amount.  In that case we would want to stretch from 20 inches (which is what we are getting) to the desired 20.2.  If that is the case, then it seems the proper percentage of stretch would be

100*((20.2 - 20)/20) = 1.0%

I await incoming.

RayW said

"try again, Jim"

Well, I would like to hear more in the way of argument than that.

My main point is that normally when we refer to a percentage change we are not talking about a ratio of intended amount to result but instead to the resultant difference or delta divided by the base value.  In that case, Mike had the correct answer for shrinkage of 35.5 result for 36 intended.  He said the shrinkage is 36/35.5 or 1.4%.  His answer is correct but the method he is suggesting is incorrect.  The proper calculation should be

100*((36 -35.5)/36) - 1.389% which rounds to 1.4%.

36/35.5 = 1.014 on my calculator.

This lead Seder to do 20.2/20 = 1.01% which is clearly wrong.

So, rayw, I would encourage you to "try again".

The only way that I can see that I am incorrect is if the definition of percent stretch is really the ratio and not the usual percent change.  If that is the case then his initial example is wrong.

In my previous post I said

"The only way that I can see that I am incorrect is if the definition of percent stretch is really the ratio and not the usual percent change.  If that is the case then his initial example is wrong."

Just to clarify, what I meant is that I am wrong if Mike intended us to use the ratio in QU instead of the normal definition of percent stretch.  But if this is the case then he is being inconsistent in his first example.
