File Requirements
All digital files linked to documents to be printed
must be supplied -- these include fonts, directly imported
images, and images placed within imported images. Include
only the most recently edited files -- disks must be clear
of all unnecessary and duplicate files.
Fonts
- All
fonts used within final documents, and within art placed
into final documents, must be supplied.
We recommend Adobe PostScript fonts for the most
reliable output. PostScript fonts are comprised of a
screen font (the bitmapped part of the font—usually in a
suitcase) and the printer font (the PostScript part of
the font). Both parts of all variations of the fonts
(typestyles) must be supplied for proper output. Fonts
used within EPS picture files must be supplied, unless
outlines were created for this text within an
illustration program. Even though Prepress has a font
library, the exact font used to create the document
insures text will output as expected. Since missing
fonts is a common problem, and manually collecting fonts
can be difficult, we suggest using a program with an
automatic font collection feature (like FlightCheck or
PreFlight Designer).
- Do not
stylize a font with a bold or italic attribute—only
use the actual font for a desired effect.
Some programs
provide a feature which allows you to apply a bold or
italic attribute to the plain version of a font. If
the bold or italic version of the font is available,
it may print correctly from a laser printer, but the
style is often lost during film output.
Documents to be printed
- Page
size should match size of printed piece before
folding.
- Folds
should work properly.
The sizes of panels & the alignment of objects
to folds should be carefully measured. Panels folding
into other panels should be slightly smaller to
prevent the panels from binding against each other.
For example, with a standard tri-fold pamphlet, the
sizes of the three panels of an 11" wide sheet
should fold to 3 11 /16", 3 11 /16", and 3 5
/8". Folds should be specified with dashed crop
marks near the edge of the page to specify the exact
panel sizes.
- 1/8"
of image should extend beyond page boundaries for
bleeds.
- Links to
any imported images must be established, and updated
to the most recent versions of these images.
- Colors have to be
correctly specified as CMYK or spot depending on the
inks to be used on press.
Since colors used within an imaging program are imported
into the layout program along with the image, planning
the use of color is necessary at the start of a project
(see specifics under Images section). In addition to
imported colors, the color palette of the final document
must be correctly edited in order to separate the
document into only the desired colors.
- Four-color—all
images and colors have to be CMYK.
For example, in Quark 3, the Process Separation box
within the Edit Color dialogue box must be selected
for all colors used; in Quark 4, the Spot Color box
must be deselected.
- Spot-color—all
images and objects must use only the colors specified
for the job.
Deleting all other colors from the color palette,
and making sure there is only one name for a specific
spot color can prevent additional colors from being
used.
- White
should not be used as a gradient value.
0% of another color within the gradient should be
used in place of white to avoid color separation
problems.
- A fill
of none should not be applied to a grayscale or CMYK
TIFF picture box in Quark 3.
Although transparent areas may appear within the
image, jagged edges will result upon output. A
clipping path should be used to create true
transparency.
- Halftone
screen angles of two or more spot colors should be
different.
If duotones or gradients involving spot colors are
used, the screen value setting for each color should
be different. Moiré patterns may result if the screen
angles remain the same. The default screen angle
values for black, cyan, magenta, and yellow can be
applied to a color in Quark’s Edit Color dialogue
box.
Images
- All images linked to the final document must be
supplied.
Images placed within art which is imported into the
final document usually are necessary (unless they are
embedded). This type of image will not be collected by
Quark’s standard "Collect for Output" feature -- as with
fonts, other software will collect this type of "twice
removed" image
Vector Images
- Colors must be CMYK for a four-color job.
Although
spot colors imported from a vector-based program can
often be converted to CMYK within a page layout program,
unexpected color shifts may occur. Using only CMYK
colors insures expected colors.
Spot colors can not be CMYK.
Objects
colorized with CMYK colors will be missing when film is
output for each spot color.
A spot color can have only one name.
If a number of programs are used to create various
items in a document, a spot color’s name must be
spelled exactly the same in all cases.
White should not be used as a gradient value.
0% of another color within the gradient should be
used in place of white to avoid color separation
problems.
Illustrator files should have "Use printer’s
default screen" deselected, and if gradients are
used, "Compatible gradient printing" should be
selected.
Both
of these choices are in the Document Setup dialogue box.
Raster Images
- Line art should be 1200ppi & bitmap.
Although
more detail can be obtained by scanning line art as
grayscale, a final conversion to bitmap mode insures all
pixels are either 100% black or white. With grayscale
line art there tends to be a hairline at the edge of the
image which is not 100% black. This hairline is
converted to a halftone when the image is output to
film, resulting in jagged looking line art -- actually a
row of halftone dots along the edge of the image.
Continuous-tone images should be 300ppi.
In order to maintain proper resolutions, picture files
should not be greatly resized within the final layout—
effective resolution decreases as the size of the image is
increased.
TIFF, EPS and trapped DCS2 files are standard formats.
LZW TIFFs, JPEGs, other compressed formats and PICTs
should not be used.
Images must be CMYK or grayscale for a four-color job.
If a monotone or duotone is to be used, the effect can be
maintained, but the image must be converted to
CMYK, or colorized in Quark as a grayscale image.
Images should not be colorized in Quark if spot colors
are involved.
Colorizing TIFFs in Quark is OK if it is a four-color job,
but the image will not separate correctly as a spot
color. A monotone or duotone created in a raster image
editing program should be used. Line art as bitmap note:
If the image is a color other than black in a spot color
job, duotone mode must be used in order to colorize it as
a monotone. The threshold adjustment function within
Photoshop can establish 100% black and white in grayscale
mode before converting to duotone mode.
Fewer points in a clipping path insures smooth curves and
fewer problems with output.
Many points on a clipping path coupled with a low flatness
value can prevent a document from printing. We suggest
leaving the flatness value blank when saving the image.
When the flatness value is blank, the
image is printed using the printer’s default setting.
When saving Photoshop EPSs: "Include Halftone Screen" &
"Include Transfer Function" should be
deselected. Only in rare cases would these settings be
used for film output. If an image is to use one of these
settings, please confirm this with a note on the supplied
print.
Any Illustrator 9.0 or higher files should be back saved
to at least version 8.0 to avoid transparency issues.
Reference Materials
Clearly label all materials being supplied with the name
of the person to be contacted if there are any
questions, including company information and phone
numbers.
Reference Prints
Prints should be provided as a reference to what the
document should look like in print
Printed from exactly the same document we are receiving.
Depending on the type of file you are providing
(color or black & white), an actual-size, color or black &
white print should be provided. If a color printer is not
available, clearly label black & white prints with
appropriate color names. Ideally, a PostScript laser
printer, or at least a PostScript printer should be used.
A working dummy should be provided when multiple pages or
folding is involved.
Print color separations.
Printing color separations can help determine if the file
is ready for press and can be color separated
properly from a PostScript imaging device. If there is a
problem outputting from a designer’s printer, often it
will not output properly to film -- troubleshooting can
begin before the file is sent. Missing font problems can
also be detected by activating only the fonts you plan to
provide when printing. This can most conveniently be done
by way of a font management utility.
Artwork to be Scanned
Clearly mark crops and final sizes for all images we are
to scan. Do not draw on the picture itself. We are
equipped with a Hewlett Packard ScanJet 6300C Scanner with
a flat size of 8.5” X 11.5". We can accept
almost any flat reflective media, Please allow extra time
for scanning and loose color proofs when
scanning is involved.
