FAQ and Tips . . .
What is the difference between Matte and Gloss Paper Stock?
Matte stock is a coated paper that has a dull finish. It is often used to make pages easier to read that are text intensive or that contain numerical charts. Gloss stock is a coated paper with a shiny or highly reflective finish. It is most often used in 4-color printing to help full color photographs, images and graphics appear more vivid, real and appealing.
What is the difference between Offset and Coated (Matte or Gloss) Paper Stock?
Offset stock is uncoated paper which is most commonly used for 1-color pages in books, reports, letters and business forms. Offset stock is usually less expensive than coated stocks which are described in 1. above.
What is the difference between Cover Stock and Body Stock?
Cover stock is the outside page and is thicker than body stock. Body stock is the inside pages and is less thick than cover stock.
What is the difference between Body Stock and Text Stock?
Nothing, body and text stock both mean the inside pages of a book or catalog.
What does the # in 70# or 80# paper mean?
It is the basis weight in pounds of a text stock type or the weight of a ream (500 sheets) of 25" x 38" sheets. For a cover stock type, it's a ream of 20" x 26" sheets. With that in mind you now know the reason that 100# cover is heavier and thicker than 100# text stock.
What is the difference between 70# and 80# of the same type text paper?
The difference between 70# and 80# is the weight and thickness of each sheet of paper. The 80# would be slightly thicker and heavier than 70#. See question 6 above for further detail.
Does weight of the paper stock effect durability and quality?
Yes, but only within the same type. For instance, let's assume you chose 70 # vs. 50# offset text stock for a newsletter. The 70# stock would be more durable over time and result in less show through of the printed image from on side of a sheet to the other. However, let's assume you choose 70# gloss text vs. 70# offset for your newsletter. The gloss stock would be more durable and result in greater ink holdout and glossier images than the uncoated offset stock.
What are the advantages of full color printing?
The highest quality and most appealing print publications are printed in full color using the 4-color (CMYK or Cyan-Magenta-Yellow-Black) digital or traditional offset printing process. In contrast, computer monitors use a different color model called RGB (Red-Blue-Green). The result is often a difference between what we see on the screen and what we see in a printed piece. Studies have shown that full color increases readership and that there is over a 60 % increase in retention with full color versus black and white. Pick from an almost endless pallet of colors to create your next high quality, impact document in full living color.
What is the difference between File Upload and File Transfer Protocol (FTP)?
File upload is transfer files via our web site, File Transfer Protocol or FTP will allow you to transfer larger files via our FTP site, using an FTP client such as CuteFTP, WSFTP, FTP Voyager or one of many other available choices.
What is the best File Transfer option?
It depends; all of them have their bright spots. File upload can be done right on the web site and will allow you to quickly send files over the Internet. E-mail will allow you to attach files and send quickly through the e-mail servers. Both File upload and e-mail can have restrictions in the size of the files being sent over the Internet. FTP or File Transfer Protocol, can handle very large files, and is very stable when transferring. Depending on the size of your files you should choose the option that you are most comfortable with.

CDL wants to answer any questions you might have. Call us, e-mail us or fax us. We will answer your inquiry quickly. Learn how to reach us at the Contact Us page.
Why doesn't my file transfer to CDL?
Sometimes files are too large for certain types of file transfers. If your file takes a very long time to transfer, you probably need to use FTP to exchange the files. FTP is very stable and quick at sending large files over the Internet.
Can I make changes to my document prior to it being printed?

No, the Turnaround Time is how long it will take CDL to complete your project. This is the time from final proof approval to when the job is ready for pick-up or shipment.
What kind of electronic file format does CDL recommend?
We can accept many different formats, but your original application files are the easiest to deal with followed by a PDF.
The native application file formats that we currently support are:
Do my graphics need to be a certain resolution to ensure quality output?
Yes, 300 dpi at the final printed size for film output and 150 dpi at the final printed size for digital printing.
Why doesn't the color on my printed materials match the color on my computer screen?
There are many factors involved when viewing color. Viewing accurate color on a computer monitor requires careful monitor calibration. Also, monitors create color using RGB light. Printing creates color using CMYK color pigments. These two processes are very different and will not yield an identical color match.
Should my graphics be saved in CMYK or RGB color mode?
For film output, the CMYK color space is required. For digital printing, either CMYK or RGB is fine, however, it is best to be consistent with your selected color mode throughout each print job.
Can you do 4 color separations from Microsoft PowerPoint, Publisher and Word?
Yes, however these programs are not designed to do so. Expectations should be set at “pleasing color” rather that “accurate color”. If you are looking for an exact color match, it is best to use professional layout programs such as Quark Express, InDesign or PageMaker.
