Title: Interpolation settings changed
Post by: BillHorne on April 23, 2014, 02:10:10 AM
I'm in the process of transferring & verifying job settings from my long time installation on a desktop running XP Pro SP3 to a newer machine running Windows 7 Pro 64 bit. I just noticed a difference, though, and wonder if it might cause any potential pitfalls:

When I click the little round blue Prints icon in Job Properties, the Interpolation window pops up and displays a Maximum value of 175 ppi instead of the 360 ppi it used to be on the old machine for Normal Prints. Apart from the Posters showing the same lower maximum ppi, all other settings in that window are the same. I will post a picture of the current settings.

Should I find a way to increase these settings back up to 360 ppi, or does it not really matter?

Hi Bill,
The numbers you quote are coming from the driver.  You went from an XP to a W7 64 machine. Chances are you had to install a new driver for W7 64.
I can get 720/720 ppi with your printer.
Here are some screen snaps... to help.
Yes, you should get better numbers in those boxes.

092 shows the 720 x 720
095 shows the settings when using a printer profile.
094 shows the settings to get 720 ppi.... if you have large prints, uncheck the finest detail box to bring it down to 360
096 shows the layout screen.... make it just like that, and leave it!

I cannot get 175,,,, you must have some other setting improper.
Anyway, give the above a try, and let us know.
PS It also would be a good isea to set your interpolator to Fusion... that's the best on the planet
Best,
Fred

Thanks, Fred, you are correct as usual, I did have to install a new Epson driver. Will tinker today and let you know what happens.

Now I see how the print driver affects the PPI settings the Qimage :-o Also, that the paper choice affects how high the quality settings can go. I'm printing on Epson Enhanced Matte paper (for which I bought a custom colour profile after printing a target, sending it off for photospectrometer, etc. etc.) which seems to have an upper limit lower than your super photo paper. But what I see in Qimage is closer to what I had before, so my workflow should be much the same as it was under Windows XP. When I print some test proofs I will find out how closely they match my previous output.

Thanks again for your help!

Bill you are close, but no cigar yet!
You are showing 338 ppi instead of 360.
See my snaps.

098 shows what you have.

099 Shows what you need for 360 ppi

100 shows the result of setting the driver as shown.
All well and good unless you have a specific need to scale the image.... I can't think of any as long as you use Qimaeg.
