Resolution for print-press

I’m having trouble resizing images without losing resolution for a Pagemaker document. I have looked at PhotoShop help, but I’m still unclear. The images are saved as TIFs and I use the Place command to put them into the document.

Can someone please advise what is the best way to resize them to fit into Pagemaker and still keep the resolution at least 300 dpi?

If coming from a web page environment, it is probably not possible. It depends on the image size – if the image size you have is appropriate size for the goal.

If you have an image size of say 300 pixels dimension, then that dimension will print 1 inch wide at 300 dpi. dpi means pixels per inch.

If your goal is to print it say 6 inches wide, then 6×300 = 1800 pixels are required. No way you can get there with only 300 pixels. 300 pixels would print 6 inches wide at 300/6 = 50 dpi, which does not satisfy a 300 dpi requirement. So in such case, you would need to start over by scanning a larger appropriate size image for the goal (to create enough pixels to be able to space them at 300 pixels per inch).

Reesa, your question doesn’t actually make a lot of sense. You don’t resize to fit a piece of software, you resize to fit a page layout.

I’m going to take a guess at what you actually mean, here: it is entirely impossible to upsample an image without damaging it. The extra information is not present and never will be – you either re-scan the original at higher resolution and if you cannot, you must choose whether the degradation that happens when you re-size the image is worse than running the image at a smaller size, or to use another image.

In fact, never check "resample" if you are going to increase the image size in Photoshop.

You can *decrease* the size of the image with resampling and get good results. Just never increase.

I hope this helps.

I was unclear also to what you actually mean….it could mean that you are viewing your lay-up in the low resolution mode and it
looks bad. Toggle high res viewing and maybe that is what you mean?

I am reducing the images, not expanding them, to fit the page layout in Pagemaker. My question is, what are the best settings to use in Photoshop to resize/reduce the images without losing resolution. They are starting at a high res (some 2400). Does that help?

For best advice: try to tell in detail what you are
doing, how you are trying to change size, in what
software.

If you have to adjust size of the image, then do that in Photoshop.
Go through Image>image size – which is the way to resize an image without changing the resolution.
Is this what you need to know?

There is a difference between resizing and reducing, and also this is different than zooming in/out.
For print you need an image resolution between 240 and
350.
Then you need to know how big (in inches) the image
needs to be once printed.
If it has to be 3×4 inches portrait, then set the image
size in Photoshop at 3×4 inches at 300 ppi.

If the image is too large, no problem, just resample it to be the smaller correct size (Photoshop BiCubic mode is excellent), and then sharpen moderately afterwards. For printing at 300 dpi, USM Radius of about 1.5 is generally appropriate.

If the image is initally too small, that’s a much larger problem.

If the image will be printed at say 4 inch dimension (fill in your number), and if you want it to print at 300 dpi, then you need an image size of (4×300) = 1200 pixels, no other answer is possible. You are not speaking in these terms, but size in pixels is the only factor important (to be sufficient to come out desired size when spaced at 300 pixels per inch).

You should create an image of this correct size (pixels) before you insert it into the page layout. You can tweak the printed size later (inches), plus or minus 10% is not a big deal, but much more sometimes is, and so the size in pixels should be in the right ball park for the purpose before you insert it.
