Client remits PDF out of Publisher - now wants to scale page up

[Richard_Sohanchyk@adobeforums.com]

Client created an 8.5 x 11 newsletter in Publisher and remitted a PDF. Now wants to resize the whole thing to 11 x 17 or whatever is nearest proportion. At 130% I end up with 11 x 14.5ish. He doesn't want to have to recreate this. I was thinking of opening in PS and resizing. This is for an art gallery so I'm real hesitant to print 1000 of these things and having everything pixellize. Client's not the savviest layout person but I initially told him it would serve him in the long run to redo the 4 pages the exact size he wants. Any suggestions if he prefers not to recompose the pages to fit larger size?

How could you open it in Photoshop and NOT have it pixellize. That's what will happen. NOT a good idea.

Tell the customer to recompose it or print it on 11 x 17 and trim off the extra 2.5".

How quality conscious could he be working in Publisher? Just rescale the thing. If they images in it are good to begin with, 130% will still look pretty good on output. If they are crap to begin with they would not have looked good at 100% either, so don't worry either way.

So, place it in Indesign and resize (if you resize in PS the text will rasterize too). If you want to make a "quality check" on the images afterwards, rasterize the pdf in PS at 300 dpi and see what the images look like (but dont use those for print, ofcourse).

Just tried this: Opened the press quality PDF in PS at 300 ppi and resized at 130%, I end up at 11.05 x 14.3 at 230.769 pixels which may be enough pixels to print clearly. I've printed spot color jobs at 230 that were okay. It's Sunday morning and I just finished affixing easel backs to padded forms for 3 hours so my brain is numb right now. Having done this kind of drudgery in a while. ;-)

I know this has been discussed ad nauseum but I have to ask. Is there a huge difference between 300 ppi and 300 dpi? These days the terms are often used interchangeably and I lose track of what's what.

While this may be an interesting academic question, so far as I can see, it has absolutely nothing to do with your present issue.

The fact is that by "opening" (i.e., rasterizing) in Photoshop, you have created a raster image of the entire page at an effective resolution of 230.769 pixels per inch. Unless your output device happens to have a device resolution of 230.769 device pixels per inch, the RIP will be resampling your just-crated image. Assuming that there are vector and/or text elements in the page, the quality will suffer as a result.

If all you are wanting to do is to scale the page up without moving any content around, why not just print it from Acrobat at an enlarged scale? Or, if you want a scaled PDF, why not place it in InDesign, and print at the scaled size to Adobe PDF (or save PS for distillation)?

This is probably what I meant to ask. Didn't think this through when I posted.

Well - back to bindery. Only 350 more easelbacks to go.

Yes, those terms dpi and ppi are used interchangably; but that adds confusion because it is wrong most of the time when we use it.

PPI: image pixel dimensions
a pixel has no physical size; it is just color information. It is the number of pixels along the width and height of an image; the number of pixels per unit of length

PPI: monitor or screen resolution
Image pixels equal to monitor pixels. How big a monitor pixel is determined by the physical monitor and the video card settings that feed info to it.

DPI: printer or output resolution
The littler physical dots per inch produced by a laser printer or an imagesetter. Pixels are translated to modulated dot sizes.

LPI: line screen resolution
Bigger physical dots at possibly 150 to the inch, for example. Halftone screens are used to reproduce images now called halftones.

When you image a page with both text and pictures, the text and solid regions are imaged at the high dpi capability of the imager; and at the same time the picture is imaged at the lpi (linescreen)--think of them as the bigger clumpier dots--some call them linescreen spots.

So, resolution has really 4 various definitions. Pixels are in no way dots.
