how to save black/wht photos

[junedonofrio]

i am just learning photoshop & i need photo's scanned for a yearbook, does not have to be top quality, but would like it to look good. i am scanning at 300 dpi, then when i get into photoshop & i go to save it, it's asking about "encoding" binary, ASCII, or jpegs, i know i dont want jpeg, but not sure on the other two options, it also asks to check one of the following
include halftone screen
include transfer fuction
postscript color management
i would guess on this include halftone screen ??
also do i have to change something on the pixels before saving ??

i am using this in quark xpress 5.0 for pc

any help will be appreciated.
thanks,
June

If you are outputting to a PostScript printer I would choose the following:-

File Type: [red]EPS[/red]
reasons: load in Quark instantly - as opposed to TIFFs and Quark file stays very small - TIFFs can make Quark files LARGE

Preview: [red]JPEG[/red]
reason: gives a better preview of the image in Quark than 8-bit colour

Encoding: [red]JPEG (high quality)[/red]
reason: will keep files about 1/10th size of original and you will not see any difference on output

If you are outputting to a non-PostScript printer then I would simply opt for TIFF files

thanks for all the info, one more question, i dont have option of picking jpeg for "preview", i am using version 5.5 of photoshop, i do have version 7.0.(not loaded yet) would it be in that one ?? also when i go to save its asking to check one of the following
include halftone screen
include transfer fuction
postscript color management would it be include the halftone screen ??

thanks again

Check with you printer for thier specifications for image files. They should, if they know what they're doing, be able to give you the file types, settings color modes etc that works for their specific printing processes.

On a side note. Quark will create a larger file if you use EPS or Tiff files. The newer Jpeg compressions (I believe 5.5 has this also) are not as destructive as they used to be. For your yearbook use the images will be perfectly fine if you save them as Maximum Quality Jpeg. IF you don't edit and re-save them more than a couple of times. Just be sure to ALWAYS save an original and work on a duplicate.

P.S. Do any of your area yearbook photographers offer digital files for yearbook publication? You may want to look into that since they would scan an original image and/or have taken it digitally in the first place. Saves you time and gets you a first generation image.

I hope this helps. Good luck.

I must say I do not agree with Chadoe. JPEG files carry no file size information (or certainly never used to) so they import into Quark at a default 72 dpi. This means that if the JPEG was saved at 300 dpi the image will come into Quark at over 4x larger than required. This is a pain in the bum. That is why a very reputable company Highwater used to create software to overcome this problem. EPS files can incorporate JPEG compression (normally Binary). Using this method the files remain tiny and import into Quark at the correct size - and the Quark file remains small and speedy.

I scan images for a living using a ICG 355i drum scanner and am happy to save almost all the work I do to high (not maximum) quality JPEG compressed EPS files. It works a treat and I cannot see any difference to the original scan. I think most people imagine that they can see degradation to the image. I once had someone comparing output to film proof (Cromalin) from a JPEG and a normal Binary file. He was checking them thoroughly for about an hour - certain he could tell the difference - and then he picked the wrong one. He was even using a loupe (eye glass). Hence I think people saying that JPEG's are not the way to go are speaking *!@£$!
