Printing film
using
a laser printer is made obsolete by inkjet technology which
uses special inkjet films & inks.
Compare...
Size/Cost
For less than the cost of a laser
printer you can purchase an Epson 4000
which can print up to 430mm wide. No laser printer can match the
printing width of the wide format inkjet printers.
You also get the further bonus of
being able to print colour proofs or posters with your inkjet printer.
Registration
A laser printer heats substrates up to 160°C
which deforms film. Registration is lost when using laser printed film due to the heat.
This means multi colour printouts are not possible.
UV density (opacity to ultra-violet light)
A laser printout has a low opacity
(low Maximum UV density) which is not uniform.
With inkjet printed film, each dot
has a UV density over 4.0 - higher than red masking film.
Quality of the output
Inkjet printers are able to produce
resolution up to 2800dpi. 1440 is usually sufficient for most film
positives.
- Ask for a film sample and judge
for yourself.
