Here is the ghostscript questions Andy!!
Gilligan:
Actually haven't even got there.
I'm following a tut on t-shirtforums and they say to install a laserjet 4/4m PS and "print to file".
seems easy enough.
Set it up, test file works (doesn't ask me where to save but a quick search and I find it saving to my profile's root)... so off to Photoshop.
Go through the motions and ... and... and... NADA!
No file created and no error. This is on my XP laptop... on the wife's win7 64 desktop it says "access denied" when I select the file name (from any app). Probably a UAC issue trying to write to the root of my profile. I would like to specify where my file would go but I don't seem to be given that option.
Gilligan:
So more playing around.
Still no luck with Photoshop.
BUT Illustrator does output separations and outputs to file (I need a better printer to fake I think).
So I took my blocks and dumped them into illustrator and outputted them... now I'm confused. Maybe this is how it is supposed to look but it seems odd.
This is blocks of 90% black to 10% black. I printed out of ghostview to PDF so I could look at the dots close up.
Can someone explain them better to me or is it like I think and screwed up?
Frog:
I rarely output this stuff from Photoshop, but rather Corel, mostly DRAW. There we have an option to output as a Device Independent Bitmap.
Forgive me if I screw this up, because as I said, I hardly ever output this way. However, there are a bunch of other members who will explain this better (if not actually correctly if I blew it)
In Photoshop, I guess I would print to file to a dummy driver, as you did. I use the HP 5500 In Photoshop, you set your lpi, and angles in each channel (just black in this case)
Print to file, then, you need to open Ghostview GS View. This is where you actually print from. I saw no mention of this, do you have it installed?
If not, get it here.
Open your file, set your media size (and orientation if needed), pick your real printer, and have at it.
Gilligan:
Ok... still not working form Photoshop. Same thing... looks like it's making the file but it disappears, never ask where to save it and it's no where to be found in a search of the hard drive.
I do have Ghostview (and ghostscript).
That pdf I attached above was from printing to PDF from ghostview (as a way to see the output, I don't have a printer at home). That was from the LaserJet 4/4M PS which resulted in strange "ellipses" to say the least.
So I grabbed the 5500 and installed it. From here I went back into illustrator and still had some problems if I choose "Separations (host based)" from the output section it was printing in a weird CMYK that was using all colors (like when working in RGB how black isn't just black but a mix) I outputted the sep and turned off all the other colors and it just had like the darkest blocks. So I tried "In-Rip Separations" (this wasn't available in the LJ 4/4m) and it worked just fine. Even made better ellipses as you can see from this attached PDF printed out from GhostView.
So should I be able to take the .ps file that created this pdf and use ghostview to output my films for my halftone test? Hoping to get some testing done today. :)
Frog:
As I warned you, I am not the guy for much help with specific Adobe/Ghost questions (hell, I'm barely helpful with Corel)
An Adobe Ghoster is bound to jump in.
A couple of things though. When I tried this in PS last night, I also could not find my saved "Print to File" file. I did a search, and did find it in my usual "Frog Jobs" folder (rather than the usual "Print to file" folder I have). Make sure you give it a specific individual name that you can search for, and figure out where PS and GS View want to put them.
Then open it in GS VIew and print.
Now, In PS or Illy, what line frequency did you use? The 40 that we suggested? I can't tell from your attachment, as except for bitmap workarounds, the line frequency is a product of the RIP upon output.
