Digital Files - problems and solutions
Problem: How to Send files
Email is a tremendous tool you can use to send us digital files for your
print job. However, there are some issues you may encounter that may cause
a few problems. Once you know what these issues are, you can be prepared
to overcome these problems. Other file transmission methods available are
FTP, or the standard storage disk, whether it be a CD-R, Jazz or Zip, to
name but a few.
Solution: Figure out the best method for your needs, and make sure
your Internet Provider can meet those needs.
Problem: How fast should my Internet
access be?
You really need a high speed connection to be able to send graphic files
over the Internet. A typical dial up connection might reach speeds of 56kbps,
while you can get speeds around 25 times faster with a DSL or Cable Internet
connection. At 56kbps, a 5 meg file would take over 90 minutes to send,
while over a typical DSL connection the same file would take only 4 minutes.
Solution: Get a high speed Internet connection or send large files
on a CD. Also, compress files with WinZip or other compression programs
to decrease their size.
Problem: File size limitations of email
providers
Many commercial Internet Service Providers (ISP) limit the size of the emails
you can send - providers like AOL and others simply cannot handle the large
files that are common in the printing industry.
Solution: Either send files on a CD-R, Jazz or Zip disk, or use FTP
to transfer large files. Use a compression program to decrease the size
of your file.
Problem: What is FTP? When should I use
it?
FTP stands for File Transfer Protocol, and it is used to transfer files
over the Internet direct to a server. While using FTP will not speed up
the time it takes to transfer your file to us, it will allow you to send
larger files that your ISP will not allow. Also, from time to time an email
may be "floating" around in cyberspace before it actually reaches
its intended recipient. FTP bypasses that - using FTP is just like copying
your file from one computer to another.
Solution: If you plan on sending a lot of graphic files over the
Internet, use an FTP program. However, if you do use it, you have to let
us know that you submitted a file to the FTP site - most FTP servers do
not automatically send the owner a notification every time a new file is
uploaded.
Problem: I am having trouble
emailing you a file. How do I do it?
Any graphic files sent via email must be "attached" to your email
message. You cannot simply cut and paste your print piece into an email
and expect it to work.
Solution: Most email programs allow you to attach a file. You may
have to experiment with some encoding settings though, to make sure your
emails are transferred correctly.
Problem: What are these encoding
settings? What is "binhex" and "mime"?
Every email gets broken up into little packets as it travels over the Internet.
The way these packets are encoded depends on how you have your email program
set up. For example, if you use Netscape, it is almost impossible to change
this setting from its default setting of "binhex". This may cause
certain file attachments to either be corrupted or to become pasted into
the text of the email message, regardless of how you attached the file.
It has been our experience that mime encoding works better with PDF file
attachments, however, we have seen problems with mime encoded emails coming
from a PC to a Mac environment.
Solution: Test your file type before you get into a pinch. Or better
yet, compress your file using a common compression program like WinZip or
StuffIt. These types of files have very few problems when attached to emailed
messages.
Problem: Macintosh or PC? Can't they
speak the same language?
No, they don't speak the same language. Windows knows
which program to open up a file with because of the filename extensions
- .doc, .jpg, .tiff, and so on. Macintosh computers do not use this extension
- they use an internal part of the file known as the resource fork. Therefore,
a Mac user may not know which program to open a PC file with, and vice versa
for a PC user. When you name a file on a Macintosh that is going to a PC,
add the appropriate file extension. However, we see many more PC created
files sent to us that we need to open on our Mac system. That is why it
is imperative that we know what software was used to create the file - we
might not be able to tell what kind of file it is just by the name.
Solution: The best way to avoid cross-platform
issues is to use PDF files. PDF files, when correctly created, will give
you a consistent print image regardless of what type of system is being
used. They also are easily recognized by both PC's and Mac's.
Problem: There is a wrong way to
create PDF files
The three most common ways to create PDF files are as follows:
Solution: Use Acrobat Distiller to create PDF files, and be sure to use the correct print-ready settings.
Problem: Why can't you use a
PDF file that is created for use on the Internet?
While anyone can create a PDF file that looks good on the Internet, printers
require a much more detailed PDF file in order for it to reproduce correctly
on commercial presses - whether they are digital or conventional. As always,
the most common problem is font substitution - if your file does not have
the fonts embedded, anyone else who views your file might see fonts other
than the ones you intended. Also, while the Internet is fine if you only
want to see 256 different colors, your file may look vastly different when
it is imaged on an offset web press that produces literally several million
different color gradations. Just remember that the image you see on your
screen or coming out of your desktop color printer will not be the same
as one coming off the end of a commercial-grade offset press.
Solution: Use the correct job option settings when creating PDF files,
and be sure to only use high resolution graphic files when designing print
documents.
Problem: Why can't you use our logo
from our web site?
Web sites are designed to load fast, and any graphic images on them need
to be just good enough to look fine on a computer screen. Printers need
files that have a much greater resolution than what is common on the web.
While you may be able to print a decent quality image of a web site on your
ink jet, if you try to print that same file on a typical high resolution
offset or digital press, you will likely have a poor print job on your hands.
Solution: Don't use web images in the print world - when designing
graphic images for your web site, have your graphics designer create high
resolution versions for printing. Typically jpeg files will not have the
resolution a printer requires - get high resolution tiff files instead.
Problem: Why is it important to "manage"
color in digital files?
Another recurring problem with digital files submitted to printers is spot
color vs. process color. We have seen jobs submitted that include 7 spot
colors in addition to process color images - that means this four color
job would have to be printed on an 11 color press! The designer of this
piece did not set up the color management parameters correctly when it was
first created in Adobe's Photoshop, and these color settings were carried
all the way through the PDF creation process. The correct procedure would
have been to change all spot colors to process color within Photoshop. We
have also seen the opposite scenario to be somewhat common - colors intended
to be spot PMS colors are sent to us as process colors.
Solution: Be sure that spot colors are truly spot colors, and process
colors should not be mixed with spot colors within the same job.
Problem: I use Microsoft Word and Excel
a lot. Can you use these types of files?
Most printers cringe when they hear that question. These standard office
programs were never intended to act as graphic design programs. If you give
us a Word file, we can't be sure that what we see when we open it up on
our computer is exactly what you see when you open it up on yours. Many
"native application" files will look different on different systems
because of varying software versions, installed fonts, and printer set-ups
(a native application file is one that can only be opened up with the same
program that created it). Therefore, we have no idea if our version of Microsoft
Word is changing your margins or page breaks, or is substituting fonts unless
we see a hard copy to compare it to.
Solution: Create an EPS file right from your Word or Excel program
by printing to a file using a Postscript printer driver. Then you can either
send us the EPS file, or you could go one step further and distill your
EPS into a PDF file and send us the PDF file. To

Problem: Why can't you edit my file
yourself?
We finally got you to send us a PDF or EPS file, and now you want us to
make some modifications to it. The fact is that the editing of these types
of files is extremely limited. The reason for this is that EPS and PDF files
are created to insure uniformity over any type of computer system. This
uniformity comes with a price, and that is editability.
Solution: Make a choice between reliability (EPS or PDF files) or
editability (a native application file). Just be sure that if you send us
a native application file, it is created with a high quality graphic design
program, like Quark or Photoshop. Any lesser programs will sacrifice resolution
and print quality.
Problem: I use Quark. Do you still
want a PDF or EPS file?
Quark, Adobe Illustrator, and Adobe Photoshop are the 3 most common graphic
design programs in use by the printing industry. If you use any of these
programs, you could send us native application files as long as you include
any fonts and high resolution graphic images - also be sure that your color
Management settings are correct.
Solution: If you can send us a complete native application file in
one of these three most common formats, then do so. Otherwise, stick with
a PDF or EPS file.
