Photoshop Procedures for Epson Photo ink jet printers using Power Macintosh
Produce accurate photographic prints from the Epson Photo 780, 820, 870,
2200, 2000P and other models using several types of Epson papers. Follow
these exact steps in order to alleviate any potential problems with color
casts and restricted tonal ranges.
Epson papers are the best media to use due to several problems encountered
with certain types of papers not accepting inks properly. This leads
to ink droplets that pool and dry on the surface rather than absorbing
into the paper. The image will also appear low quality due to a
loss in sharpness and detail. Kodak papers are notorious for this
type of outcome.
Epson Photo Paper, Semi-Gloss, Archival Matte, Photo Luster, Velvet Fine
Art and Watercolor are all high-grade papers. The Archival Matte
paper will preserve dye based inks for a longer period of time (25 years),
compared to the Photo Paper (7 years). For other ink jet paper

*Finalize your image document in Adobe Photoshop using the Unsharp Mask
filter. Be sure to check the highlight and shadow areas for adequate
detail. Any image area that registers at a value of 255 in the highlights
will lack any printer detail. Detail will also be lost in shadow
areas if the black point of the image registers at a value of 0.
For Best Results Use Epson Papers:
1. Standardize the color space of the document by embedding an
ICC profile to the image. First, navigate to the Image>Mode>Assign
Profile menu.
In the Assign Profile window,
select "Adobe
RGB (1998)". This is the widest color
gamut recognized in the industry.
* Toggle the Preview checkbox to determine if there is a significant color
shift on the image due to any profile conversions. If so, it is possible
that the image has been scanned and embedded with a pre-assigned profile
that restricted its color space. In this case, it may be best to print
from the already pre-assigned profile or attempt a rescan. Consult the
scanner software preferences to ensure that the color space is set to
Adobe RGB (1998).

5. Click on Print in
the Preview window. In the Epson Print window, choose the correct Media
Type in the drop down menu (ex.
Archival Matte Paper). In the Ink area select Color. Choose Custom Mode
and press the Advanced button.
* Selecting only Black ink for printing B/W images will eliminate forms
of metamerism, but produces less dpi precision resulting in detectable
ink dots.

6. In the Advanced window, choose the Print Quality (720 dpi
for drafts, 1440 dpi for portfolio work). In the Color Management area,
select No Color Adjustment and press the OK button.

Note-
Fresh ink jet prints will take about 15 minutes to dry, and may appear slightly
dark immediately after printing. Ink jet prints dry slightly up in density
and will reveal crucial shadow detail once dry. This is the exact opposite
of traditional photographic prints.

B/W Images
Certain color casts are detectable when printing b/w images on standard
ink jet printers. This characteristic occurs because CMYK inks are used
to reproduce and simulate black and white tones. Dedicated b/w piezography
quadtone
printers are a recent solution to eliminating unwanted color detection.
These specially formulated systems are only available as a dedicated conversion
kit for several designated Epson
printers. The quadtone process employs high-performance quad black inks
with additional hardware and software to achieve a neutral photographic
result.
Metamerism
Metamerism
is a color shift that is detectable when images are displayed under a
variety of lighting conditions. Printers that employ pigments encounter
more of a color shift than most standard dye-based ink jet printers. Final
prints can take on color shifts ranging from a cool green to a warm magenta
when displayed under a variety of light sources. The Epson 2000P uses
pigment based archival
color inks expected to last 200 years. A high precision piezography
process weaves a fine web of detail by sending an electronic charge through
specially designed quartz crystals that change shape and squirt microscopic
droplets onto a paper medium. Giclée
is defined as a fully archival piezography process that employs paper
mediums such as watercolor and canvas for reproduction.
