Accurate on-screen sharpening?

[Kevin M]

At one time it used puzzle me greatly why Print Size zoom and actual print size didn't tally on screen - until I realized that I had made the common error of forgetting to enter my 'true' screen resolution in the Units and Rulers tab of Photoshop preferences. At the time it was set up automatically at 72 instead of the correct 92 of my monitor resolution. Once I made the correction sizes of print and grid lines etc all became exactly correct when using Print Size zoom.

However,  I still find that precisely evaluating sharpening  is best done by making a small test print of some relevant detail.

OMG DOOOD!  

This has been driving me NUTS!  THANKS SO MUCH for that tip.  ...props to you on my site:  www.teddillard.com!



(Kind of like that thing where having the Caps Lock on sets all your brushes to Precise.  Took me a lifetime to figure that one out, too.  damn!)

back atcha...  this site will calculate your actual ppi, using your screen "resolution" and your diagonal dimension.

Thanks for the useful link, Ted.

As I recall, at the time I had only a vague idea of what my actual screen resolution was. To check I put a print file on screen with a 1" grid overlayed  and kept changing the screen resolution in Units and Rulers until the 1" grid coincided with markings on my ruler at Print Size zoom. Very scientific.

That's very resourceful!  And here I was feeling goofy holding a ruler up to the screen..  

Thanks again for that.  Can't believe how long I didn't know that.  Just goes to show, there is a way to do everything you can imagine in Photoshop, I figure...  you just have to find it (or benefit from someone else finding it!)

Can you enlarge on that?

My understanding of it is that Photoshop divides print resolution ppi by screeen resolution ppi to give the appropriate zoom percentage when Print Size view is selected.
To have print measurements and screen measurements tally - the correct screen resolution ppi of your particular monitor has to be entered in the appropriate box in the Units and Rulers tab of Photoshop preferences.
