Digital File Prep Information
The following
information will help you prepare your electronic art files for effective
and efficient processing by Johnson Printing.
One of the greatest obstacles to successful printing from digital
art is improper file preparation. File testing is at no charge and identifies potential
problems that must be resolved before going live. A simple test file containing at least one left-hand and one right-hand page
is all that's needed to make certain that the process works for the customer and the printer alike.
In order to manage digital prepress production and meet press schedule commitments, we must know the details regarding your
files. Once a job is live, if we discover a problem with your
files you have the option of repairing them, or you may authorize
JP to perform the work at the rate of $85/hour. Changes, repairs,
or delays may affect the project schedule. Your complete satisfaction
is our goal!

General
Rules & Guidelines
- All process color images must be in
CMYK format (process colors are Cyan, Magenta, Yellow & Black), not RGB (Red, Green, Blue). In order to proof and print
to your satisfaction, RGB files must be modified to CMYK. If RGB color files are submitted, additional costs may be incurred and your schedule may be disrupted
CREATING POSTSCRIPT & PDF:
The standard process is to save the
file as a Postscript file, then distill it to a PDF file, using
the recommended PDF settings & procedures. Documents specifying how to create
Postscript and PDF are available on this site
- When creating PostScript from layout applications, make certain that all image files
are TIFF or EPS (not PICT, GIF, JPEG, etc.). Color space must be CMYK or grayscal (not RGB). Font types should be Type 1
PostScript fonts (avoid Truetype and other fonts). Use 8-bit ZIP for compression (avoid JPEG and LZW). For more detailed information,
see PDF settings & procedures
- Your document (page)
size should be the same as the finished trim size of your
book. Pages that are not sized the same as the finished trim size must be modified. As a
result, additional costs may be incurred and the schedule may be disrupted. This is a common
problem in web printing due to final trim sizes of 8.375"x10.875" (or digest size of
5.375"x8.375"). When the web process is used for any portion of your product, all artwork must
be set up for this size, not 8.5"x11" (or digest size of 5.5"x8.5"). Another example of a page
that requires modification is a smaller page (e.g., 6"x9") placed in a larger (e.g., 8.5"x11") template.
- Make certain that adequate space is maintained between
non-bleed page elements such as type & graphics, and the page edge. A minimum of 1/8" is called for
on sheetfed work, and 3/16" on web work
- Set up your files
with the actual margins you want in the book
- Bleeds must
be a minimum of 1/8" beyond trim for sheetfed work, and 3/16" for web work.
In either type of work bleed should not extend more than 1/4" beyond final trim
- Please do not apply
trap to your artwork. Trapping is performed during raster
image processing
- When using spreads,
always use reader spreads instead of printer spreads
- Do not include crop
marks
- Do not specify rules
as "hairline", as this option is resolution dependent (i.e.,
the higher the resolution the thinner the line) and the appearance
of the finished product may not be as desired. Suggested minimum
line weight is 0.25 pt.
- Placed graphics
should be PostScript compatible (e.g., TIFF or EPS). Other formats
such as PICT, WMF and others, may be problematic. If you have
questions about your graphic files please contact your JP representative
for information

File
Organization
- To ensure
we meet your deadlines, a little advance file organization and
preparation goes a long way. Properly prepared files also help
minimize additional charges. If you utilize "collect from output" in Quark XPress,
"save for service provider" in PageMaker or "package" in InDesign, these functions will
automatically perform the file operations listed below. Following are simple step-by-step
recommendations for organization and preparation of your art
- Create a
folder named Johnson
- Create two
folders within the Johnson folder, named Fonts and
Graphics
- Place all
fonts and graphics used in your document in these folders. Do
not place other fonts or graphics in these folders, only those
that you are using on the current project. Check to make sure
any fonts used in EPS graphics are also included in your font
folder
- Place the
file(s) to be printed loose in the Johnson folder. Always use
consistent, logical naming conventions for your files
- In addition
to your files, also submit complete and current hard copy of
all pages and other elements of your project
return
to top
File Naming
Convention
-
File names should contain only letters, numbers,
underscores, and periods
-
Limit file and folder names to a maximum of 31
characters
-
Please rename any files that contain spaces and other
illegal characters such as: \ / : * ? & " < > |
-
Some other characters, such as hyphens (-), cause problems
when transferring files and also should be removed. Renaming files
and directories to include only letters, numbers, and underscores (
_ ) will eliminate any potential problems
-
Use only one period per file name. The period needs to
be right before the filename extension. Use the underscore to
substitute for any extra periods
-
Use correct filename extensions. Operating systems
associate filename extensions with specific software applications.
Adding the correct file extension to your file names will eliminate
the need for you to choose an application when you open your
document
-
Revision or correction files should be clearly identified to distinguish them from prior versions

Fonts
- All fonts (screen and printer) must be provided. If fonts are
not supplied and are loaded by JP, additional charges may be incurred and text reflow may occur
- Supplied
fonts are used only for your work and are removed from our system
after completion of your project
- When using
Macintosh fonts be sure to include screen and printer versions
of Postscript fonts. *TrueType fonts consist of one item
- Windows fonts
are typically found in the “/windows/system” directory. Select
only those you have used and copy them to the font folder you
have created within the Johnson folder. For *Postscript fonts
select the font with both “.pfm” and “.pfb” extensions. TrueType
fonts have a “.ttf” extension
- Check to
make sure fonts used in EPS graphics are also included in your
font folder
- Do not use
stylized fonts (i.e., styles such as bold-italic applied to a
plain font), unless you're supplying the font, because the style will drop out in the process if the printer font isn't supplied. Instead,
select the appropriate font from the font drop-down menu

return
to top
Color Application
- Be aware of the color system you're using, which will affect
whether you must identify color as separation or spot. Enter the actual CMYK percentages when specifying process tint matches to PMS colors, as
different applications often generate different percentages and tints. Make certain you remove incorrect and unused colors
from your document's color palette

Supported
Software Applications
To ensure that we consistently produce work that meets or exceeds
requirements, it is critical that the input is of a type that enables
us to do so. JP supports native file formats of all professional page
layout and graphic arts applications on Mac and PC platforms (except
where noted). Supported applications and release level include:
- Adobe InDesign CS, CS2
- QuarkXpress 6.5
- Adobe Pagemaker 7.0
- Adobe Acrobat 6.0
- Adobe Illustrator CS, CS2
- Adobe Photoshop CS, CS2
- Corel Draw 11.0 (Mac & PC)
JP uses the most current version
of each listed application once it has been thoroughly tested and proven to function properly within the digital prepress
environment. If you have a newer version than listed, please contact your JP representative prior to submitting files.
Use of older versions is not recommended as they may yield unsatisfactory and/or unexpected results.

Non-Industry Standard
Applications
Word processing programs, applications not listed
above and non-desktop publishing programs should not be used to create native
files. If such files are submitted, additional processing charges may apply. They can be used as source files and formatting charges will apply. Examples include MS Word, Word Perfect and DTP programs
such as MS Publisher. We may accept Postscript or PDF generated from
these files. Contact your JP representative for assistance.

Submitting
Files Via FTP
- Contact your JP sales
or customer service representative and apprise them that you wish
to FTP files to JP. Your JP rep will provide you with a username and password. Keep these in a secure file, as they'll be required each time
you access your directory
- The JP system administrator will generate a
directory for your organization (if one doesn’t already exist)
- To FTP: The address
is ftp://ftp.jpcolorado.com and your
directory will reside in public/“your company”
- Some browsers support
FTP uploads-others don’t. If you use a browser that doesn't support
FTP you'll need to use a program specifically designed for FTP
transfers. Acquire a program such as Fetch for Macintosh or WS-FTP
for Windows. If your browser supports FTP uploading, it should also support
“drag and drop” of your files
- Once you have transferred
your files, contact your JP sales or customer service representative
again to let them know you have sent the files
Note: Please limit the upload file size to 50mb.
Although you could send larger files through a T1 line, we ask
this to control traffic volume. Larger files should be sent via
disk
- All files must be stuffed or zipped to ensure file integrity during transfer
- FTP access is available 24-7 via T1.
Files sent via FTP must be compressed and saved in a self-extracting format (PC files should be encoded with *.zip).
Please consult with JP's prepress department to obtain transmission authentication
- Live and test files can also be submitted via
PDF JobReady

Metafiles
A metafile isn't an acceptable file type and should be completely
avoided. A metafile is essentially a "copy" and "paste" Windows
system graphic. It is convenient because one can move a graphic
or image from one program to another with the push of a button.
Problems arise in high-resolution workflows wherein Metafiles may
drop out, appear at lower resolution, or print incorrectly. Metafiles
do not utilize a disk file or link, so if there is an alteration
to be made to the graphic we cannot edit it. Because of the problems
inherent in metafiles JP can't safely accept digital documents that
contain them, nor can we be held responsible for quality/integrity
throughout the process - even if the proof shows the image(s) correctly.
As an alternative, save the graphics using another
method that works in prepress systems (i.e., EPS, TIFF). If you do choose to supply metafiles, JP can requote
the work to be performed, including services such as scanning of affected pages or
specific graphics.

Proofing
Tips
You've invested
a substantial amount of time and money into your project, and there
is one very important pre-production step that calls for at least
as much attention as any preceding activity. That activity is, of
course, checking your proofs and making corrections before the project
moves too far through the production pipeline to make changes economically.
The proof is the last look prior to commencement of presswork. Therefore,
a correction that is made on a page proof may cost just $10, but
the same correction may cost ten times as much if made on the digital
blueline and one hundred times as much if made once the job is on
press. The best course of action is to begin by submitting complete,
correct press-ready digital files as well as a current laser print
of your project, then refrain from making changes thereafter. In
addition to adding cost to the project, changes may also affect
your production schedule.
What sort of items should you look for when reviewing proofs? Here
are the primary items:
- Do the fonts look correct?
- Are there any low-resolution images?
- Are pages in the correct
sequential order?
- Is the correct copy
used?
- Is there any reflow of copy?
- Does all art appear
as designed and specified?
- Are all elements positioned
on each page as specified?
- Are halftones cropped
as specified?
- On bound products,
is the inside margin adequate? (This is particularly important
on wire-o or loose-leaf books, since drilling or punching may
interfere with page elements if inadequate space is allowed)
- If two or more colors
are specified, are the color breaks correct?
If, when
looking at your proofs you determine corrections need to be made,
following are a few recommendations on how to mark up the proof:
- Use a permanent red
marker, such as those available from your JP rep
- Indicate pages that
require corrections with a paper clip at the top of the page.
Although some people like to use Post-it® notes, they are more likely
to fall off during handling
- Write legibly and
err on the side of more descriptive information than might be
deemed necessary
- If you make changes
to a digital file make certain you submit a new laser page showing
the change
- If you conduct your proofing using a PDF Softprooof,
JP will output a hardcopy proof for print production reference. After you complete
proofing your softproof, please email your JP customer service rep to confirm approval, alterations, etc.
If
your corrections are extensive or complicated, your JP sales or customer service representative
will be glad to review them with you in person. If that is not possible,
reviewing the corrections over the telephone with your JP customer
service representative is the next best thing. After you have completed
the review of your proof, please remember to sign the accompanying
proof card. Your signature confirms you have reviewed the proof
and is an acknowledgment that you have found the proof to be error-free,
or that it requires the noted corrections prior to printing.
Once again,
take your time, review your proofs carefully, and a successful outcome
will be yours!
