1. Re: High Quality Preview
Stix Hart Mar 30, 2011 2:02 PM (in response to Canned Pug)What is the "Effective PPI"? You find it in the links panel in CS5, or info panel in CS4 or earlier.

2. Re: High Quality Preview
Canned Pug Mar 30, 2011 2:08 PM (in response to Stix Hart)All the images in my manuscript are at least 300 and none of them are
viewing high quality. They have been up to now so I'm thinking it's
either a setting or a memory problem.

Canned Pug Mar 30, 2011 2:09 PM (in response to Stix Hart)vector text etc = ok...raster images are the problem...

4. Re: High Quality Preview
Canned Pug Mar 30, 2011 2:15 PM (in response to Stix Hart)Would "Live Screen Drawing" have anything to do with it like in the
earlier post? Problem is, is that I'm in CS3 and can't find that
preference.

5. Re: High Quality Preview
[Jongware] Mar 30, 2011 2:19 PM (in response to Canned Pug)Live Screen Drawing is a CS5 option.
How do you know the images don't display in their native resolution? Maybe they are as bad as you think they are.

6. Re: High Quality Preview
Stix Hart Mar 30, 2011 2:20 PM (in response to Canned Pug)CS3 doesn't have that preference. You're not seeing normal behaviour, have you tried replacing your preferences?

7. Re: High Quality Preview
P Spier Mar 30, 2011 2:23 PM (in response to Canned Pug)Please select an image and do two things: Right click and see if there is an object level dispaly setting in effect, and also open the info panel and check the effective resolution. The "actual" resolution is irrelevant in this case.

Canned Pug Mar 30, 2011 2:23 PM (in response to [Jongware])becasue they weren't that way yesterday...I've worked my *** off
assuring that..

9. Re: High Quality Preview
Canned Pug Mar 30, 2011 2:26 PM (in response to [Jongware])...and also becasue even though I have a dual processor, whenever I'm
working both PS and ID together with these huge files, everything is
sticky, including trying to close aps, getting to the desktop, etc.
Maybe I'm blowing out the RAM but don't know if that's a function of
High Display..assuming it is. But when I turn off PS, I"m still having
the problem.

10. Re: High Quality Preview
Canned Pug Mar 30, 2011 2:29 PM (in response to Stix Hart)Yes, that's an option that I can do though I did it about a week ago.
Guess things can get messed up quickly if there's been a big load
on...didn't want to close everything out this soon in the day. Maybe
tonight. Thanks.

11. Re: High Quality Preview
P Spier Mar 30, 2011 2:32 PM (in response to Canned Pug)High quality display definitely taxes the system more than typical, especially if you have a lot of images.
You mentioned they weren't printing well. Is that direct from ID? Check the print dialog to make sure you change from the default value for Send Image Data, which is Optimized Subsampling, to All.
-
12. Re: High Quality Preview
Canned Pug Mar 30, 2011 2:40 PM (in response to P Spier)Effective is 315ppi...There are 3 places to set display that I can
find and I set them all to high and allow object view:
1. in Preferences checked option for object level
2. Object > Display Performance > set at High (was at "use view
setting"...no diff)
3. View > display Performance High
none of these change anything...am I not doing something right?

14. Re: High Quality Preview
P Spier Mar 30, 2011 2:48 PM (in response to Canned Pug)Are the links showing as up to date in the links panel?
-
15. Re: High Quality Preview
Canned Pug Mar 30, 2011 2:50 PM (in response to P Spier)ok, granted I have HUGE images for 26" spreads...
The printing.......it was on Optimized Subsampling..and since I don't
know about this setting, what have I been missing in my printing
before this...I don't recall ever having a quality printing problem
before...So does changing to "All" change other settings in other
dialog boxes, Epson and/or ID?..
While I do let ID handle the color, in this case I went to the printer
dialog box when I want to run quick B&W image, so uncheck Color and
set to to Greyscale and High Speed, but the quality is Normal not
Economy.....?
Maybe the quality prolems in viewing and printing are coincidently bad
but not connected in this case?

17. Re: High Quality Preview
Canned Pug Mar 30, 2011 2:57 PM (in response to P Spier)You got it Peter! though I don't know why this is so as I'm constantly
updating certain images as I'm working them...guess I didn't check on
these others.....and I had even gone to another ID file that was also
bad...and also unlinked...
Gawd, what an amateurish mistake!
S.M.N!

18. Re: High Quality Preview
P Spier Mar 30, 2011 2:59 PM (in response to Canned Pug)Well, that was about all that was left...
-
19. Re: High Quality Preview
Canned Pug Mar 30, 2011 3:18 PM (in response to P Spier)ok so that was the print problem as well. I printed out with the "All" set and it looks great.
Should I be leaving the setting to "All" all the time unless I want a quick low quality image? What would be the diff if set to Opt Sub sampling? (don't wanna waste ink to find out! ;o)
Thanks once again Peter...and all you others for all your help...
Aw...

20. Re: High Quality Preview
P Spier Mar 30, 2011 3:33 PM (in response to Canned Pug)Print one page and see is all I can tell you. It may not be a lot better, and it will slow down the print process. That said, whenever we see psots that image quality is poor in printouts, if it isn't links missing or out of date, it's optimized subsampling.

21. Re: High Quality Preview
Canned Pug Mar 30, 2011 3:38 PM (in response to P Spier)Cool...Something else I never heard about. I feel like I'm walking a
highwire across the Grand Canyon hoping I don't fall in before I reach
the other side!

22. Re: High Quality Preview
John Hawkinson Mar 30, 2011 4:05 PM (in response to Canned Pug)Optimized subsampling is tricky. If everything works properly, you should be able to leave it on and it will not adversely impact the quality of your output, and it will make your print jobs faster in many circumstances.
But everything does not always work properly.
InDesign consults the PPD (PostScript Printer Description) file associated with your printer, and reads the default resolution associated with the printer. It resamples images that are greater than that resolution to that resolution. That means it does not need to send large amounts of data to the printer that would be wasted.
But sometimes the resolution reported by the PPD file doesn't match what your printer is using. Or maybe there's a weird artifact in the resampling process. Or your printer's PPD doesn't specify a reoslution and InDesign makes a bad guess. And those are the cases where it can go wrong--sometimes terribly wrong.
So don't use it if you need 100% accurate proofs, but if 98% accuracy is OK, maybe it's a good idea, especially if your printer's network connection is slow.
