To
achieve the best possible printed results, please use the following guidelines
when preparing your artwork.
- Supply
electronic art rather than mechanicals or
film negatives.
- Build
the artwork in a page layout program with placed
photographs & EPS graphics
- Include
all fonts (printer & screen) or if type is
in EPS graphics files, convert it to outlines.
- Avoid
placing type & line art directly into Photoshop
files.
- Supply
a customer approved proof to match for color.
- Supply
a composite proof, b&w or color, so we
have a hard copy of what the final layout should look like.
- Match
PMS colors to the stock that the final product
will be printed on (coated or uncoated)
- Convert
RGB images to CMYK and proof them before including in artwork.
- Do
not use rich blacks, our inks are very rich &
dense.
- When
creating clipping paths, do not use the "magic
wand" tool.
- Build
artwork to suggested mechanical sizes and
resolution.
- Do
not trap your artwork, we will apply the appropriate
trap.
Supply art in Electronic form
rather than as film
Through each step of the printing process, from enlarging the image
to exposing the screen to actually printing on the substrate, the image
and dots are subject to "gain" and "loss". Gain
is the process by which the dots of ink grow larger than they should
be and loss is when the printed dots become smaller. Through extensive
testing and years of experience, we know how much gain & loss to
expect when an image is printed on our presses. By adjusting the image
before we make our films, we can account for the changes that occur
during printing. If you supply film negatives, we cannot make the necessary
adjustments to ensure the closest possible match to your proof.
Build the artwork in a page layout
program
The preferred
platform and method of building artwork is in Mac based QuarkXpress.
The mechanical should be built to the appropriate size with placed Photoshop
TIF or EPS photo files and placed Illustrator or Freehand EPS artwork
files. The type can be set in either Quark or as an EPS artwork file.
If you prefer to build the artwork completely in Adobe Illustrator
or Macromedia Freehand, that's fine too. Just build it to the same size
as listed on our spec sheet. Whenyou save the final file, do not embed
the photographic files in the final file, just have them linked. That
way, we can easily make the required adjustments to the image to account
for press gain & loss.
If you build the file in CorelDraw, there is no way to just link the
image, so be sure to send along a separate copy of the image file.
Include all Fonts
When you gather the files to send to us, be sure to include printer
and screen font files for all of the fonts used in your artwork. Though
we have thousands of fonts on file ourselves, if we don't have your
exact version, the spacing or kerning or some other aspect of the artwork
could change. If you have built all of your type elements in Illustrator
or Freehand, you can simply convert them to outlines or curves before
saving the EPS files. If you do that, we won't need your font files.
Bus remember, if the artwork is built in a page layout program like
Quark or Pagemaker, we must have all of the fonts.
Do not place type & line art in photographic
files
Type and line art are in computer terms "vector artwork"
- this means that the computer sees them as a series of straight lines.
Photographic files are pixels or rasterized artwork - this means that
the computer thinks of them as a series of dots. When an art layout
that contains both photographs and line art is printed to a film imagesetter,
the imagesetter takes care of rasterizing the line art with such small
dots that the art remains clean and crisp. When you place type or line
art into a Photoshop file, your computer rasterizes the line art (converts
it to pixels) at a much lower resolution than does the imagesetter.
This results in type and art that is "jagged" or bumpy. Though
the jagged edges may not be noticeable at a small size, when the artwork
is enlarged 6, 8 or 14 times, it can become very noticeable. That is
why it is best not to place type and line art in photographic files.
There may be times when the only way that you can add a special effect
is by placing the type in Photoshop. When doing so, please try to work
with the highest resolution files possible.
Supply a Customer Approved proof
There are numerous proofing systems in use today. We regularly receive
proofs made with Imation/3M Matchprint®, Kodak®, Fuji®, Agfa®, Iris®,
Rainbow®, and Dupont® systems to name just a few. Internally, we use
Iris digital proofs as well as Imation/3M Matchprint and Colorkey. Each
proofing system yields proofs of the same image that look different.
The only way that we can know what you are expecting is if you send
us a proof that you have approved. Even if you don't have a color correct
composited proof of the final artwork, you can send us a "random"
or "loose" color proof. This is a proof of the photographic
image that you have approved for color. With your proof in hand and
using our internal proofing systems, we can adjust the artwork so that
the final printed piece will look as close as possible to what you are
expecting to see.
Supply a Composite proof for
layout approval
In addition to an approved color proof for any photographic images
in your artwork, we also need a composite mechanical proof to check
the layout. When dealing with electronic files, it is very easy for
objects to move, type to become mis-aligned, etc. To be sure that nothing
has moved when we open your file, please supply a composite proof, even
if it is only a black and white laser print. If the approved color proof
that you supply is complete with all of the type and other elements,
we do not need an additional mechanical proof.
Match PMS colors to the stock used
Depending upon the color, there can be drastic differences in color
between coated and uncoated PMS colors. When picking or specifying PMS
colors, be sure to use the appropriate PMS book for the stock that will
be used. Most billboard posters are printed on uncoated 70# wet strength
paper, so when choosing colors for a billboard, choose the "U"
or uncoated colors. Bus side posters are printed with UV inks on vinyl,
which has the properties of a coated stock, so the "C" or
coated colors should be used. To find out which colors to choose from,
check the spec sheet for the product in question. Below the name of
the stock, either "coated" or "uncoated" will be
shown in parenthesis.
Convert all RGB images to CMYK
RGB images are shown with the Red, Green and Blue pixels of your computer
monitor. Printing is done with Cyan, Magenta, Yellow and Black inks.
Because the same image can be made with different colors, it won't always
look the same when in RGB mode as when in CMYK mode. With some colors,
bright fuchias and purples for instances, the change can be drastic.
For that reason, it is very important that you convert any RGB images
to CMYK in Photoshop and then view and proof them before including them
in your final artwork. If you send us an RGB image and we then convert
it to CMYK for printing, the end result might be different than you
are expecting. If you need help with this conversion, please call our
graphics department for assistance.
No need for rich blacks
Though
offset printing puts down a very thin layer of ink and requires the
use of "rich" blacks to achieve a dense black color, our inks
go down thick and look rich by themselves. When building your file,
black type should be specified as 100% black with no other color and
black backgrounds should be built the same way.
Create clipping paths with the
Pen Tool, not the Magic Wand
When creating
clipping paths in Photoshop, it is often tempting to use the Magic Wand
tool. Though a quicker method than using the Pen tool or Selection tool,
the results are not good. The Magic Wand tool typically creates a clipping
path with so many nodes that most imagesetter RIPs will not properly
process the file. To be sure that the clipping path is done the way
you want it and that the file can be processed, use either the Pen tool
or the Selection tool. If you need help with any of these tools, feel
free to call our graphics department.
Build artwork to the proper
mechanical size & resolution
Though we can easily resize your artwork if it is the wrong size or
proportion, this introduces one more place for a problem to arise. It
is also important to give us the proper resolution for any photographic
files. The proper resolution required is listed on each spec sheet.
Files with a lower resolution than listed can result in a lower quality
final product. No need to go too high with the resolution either - a
higher resolution than needed will not improve the look of the final
product and will only slow down your computer system and take up more
space.
Do not trap your artwork
As part of our pre-press workflow, we automatically check all elements
for trap and apply the appropriate size trap for the product being printed
and our printing process. Therefore, any time that you spend trapping your document
will be time that could have been spent on another project.
