Hi Rasta,

The PDF will be fine IF it prints out at the right size and your printer can print the blacks dense enough.

Some general tips I use for printing layouts which may help people...



I use an Epson photo printer (although I think any ink jet will do).

Use inkjet transparency paper (I bought mine from W.H Smiths - own brand).

Set the printer to black and white and use the best quality photo mode it has (This puts more ink down).

Make sure there are no blocked jets.

Put the paper in the printer, print and apply light pressure to one side has it feeds in - we need to do multiple passes and want to be sure it feeds identically each time.

Give the paper some time to dry, then repeat the above for another pass applying the same pressure in the same place to guide the paper in as it feeds. (It's not a bad idea to 'blot' the paper with a sheet of normal printer paper to remove any 'sticky' ink off the top between passes)

You should now see the blacks are pretty solid. If you want to be absolutely sure you cand do a 3rd pass - however I find it takes all night for the ink to dry enough before this becomes possible.

You should now have a high quality transparency, the rest depends on the photo board you use, chemical strengths etc. If in doubt it's not usually a bad idea to do exposure tests with scrap board similar to what you'd do in old fashioned photography.

Hope this helps.
