What is (4 over 1) or (4 over 4)?

  • 4/1- Four over one = Full color on the front & 1 color on the back.


  • 4/4- Four over Four = Full color on both the front & back.


  • 4/0- Four over zero = Full color on the front, but no color on the back.


What is Pantone Matching Systems (PMS)?

What is Pantone Matching Systems (PMS)?

Pantone (PMS) is the color chart used by printers. Pantone colors are mixed ink colors, identified by a number. This number when used with their “Formula Guide” specifies a mix of certain component ink colors that the printer mixes to put on the press, like mixing paint.  PMS match books are books of color where each PMS color has its own name or number that helps you make sure that your colors are the same each time you print, even if your monitor displays a different color or if you change printing services.

Pantone has several swatch guides. The most commonly used are:

  1.     Coated – Glossy Paper, Satin Paper, Dull Paper.
  2.     Uncoated – Flat Paper, Vellum, Smooth Paper.
  3.     Metallic – Foil Material mounted to Flat Paper.


What other types of inks are there?

  •     Metallic – Ink containing powdered metal or pigments that simulate metal. This effect is best  achieved on coated paper.
  •     Fluorescent – Produce vibrant and bright colors, however they do not retain their colorfastness as long and may not be suited for big quantity jobs.
  •     Soy Based – It is made from soybeans and it is environmentally friendly. It is slower to dry than many inks and it is expensive.


What is Flat Size?

Flat Size refers to the size of a product after printing and trimming, but before it has been folded or binding.

What is C1S / C2S?

C1S – Short for ‘Coated One Side‘, refers to paper that is coated on one side only.
C = Coated / 1 = One / S = Side

C2S – Short for ‘Coated two Sides‘, refers to paper that is coated on both sides.
C = Coated / 2 = Two / S = Sides

How do I use the Enhanced Upload Engine?

Getting Started

The Enhanced Upload Engine requires Java. You can download the free Java software from www.java.com/getjava/.

Using the Upload Engine

  1.     You can add multiple files to upload by either dragging the files into the window or by clicking the Add button.
  2.     You MUST then click the Start Upload button for the files to be  transferred.
  3.     As files are successfully uploaded, a message will appear below the upload engine. Make sure that all files appear in this list. You can upload as many files as you like. Once you are finished uploading, your order is complete.

If the engine does not load correctly, use an alternative upload method. Links to our alternate upload methods appear at the bottom of the page.

NOTE: It is highly recommended to compile all your files (images, layout, fonts) in a folder and then compress it to either a ZIP (.zip) format or SIT (.sit) before uploading them to our FTP server.

What is Coating or Finishing?

It is a protective layer that increases the durability and aesthetics of your printed piece. You cannot print (ink-jet or by hand), glue, or foil stamp over coatings, so you need to leave an uncoated window if you want to do any of these

There are several types of coating:

  •     Varnish – Varnish is essentially ink without pigment. It comes in gloss, dull, and satin


  •     UV Coating – UV Coating is a clear liquid spread over the paper like ink and then cured instantly with ultraviolet light. It can be a gloss or dull coating, and can be used as a spot covering to accent a particular image on the sheet or as an overall (flood) coating. Keep in mind that this thick coating may crack when scored or folded.


  •     Aqueous – Also known as AQ, is water based. It has better hold-out than varnish and does not crack or scuff easily. Aqueous does, however, cost twice as much as varnish. Aqueous comes in gloss, dull, and satin.


What is Saddle Stitch Binding?

Saddle Stitching

Most common type of binding, is stapling sheets together where they fold at the spine. They are commonly used for Booklets, brochures, newsletters, pamphlets, direct mailers, magazines and catalogs.

Saddle Stitch BindingAdvantages

  •     Fast & Inexpensive [least expensive of all binding options].
  •     Widely and readily available, since most printers saddle stitch in-house.
  •     Lays relatively flat.
  •     Accommodates special inserts like business reply envelopes, membership forms, order blanks.
  •     Gatefolds and foldouts are possible.
  •     Can use a self or separate cover.


  •     Longevity. Not recommended for pieces intended for heavy use.
  •     Lacks printable spine.
  •     Not possible to bind in a single leaf of paper [as in perfect binding], but single leaves canbe stitched into a saddle stitched book if it has a 3.5″ inch flap, or extension.
  •     Thickness limitations. Documents thicker than 0.25″ inch may require another binding technique.
  •     May require special design adjustments for creep, especially small formats with high page counts.


  •     Signatures are folded with a bind fold [a fold in the paper, which allows a mechanicalor suction device to find the center].
  •     Signatures are opened with suction cups or mechanical grippers.
  •     Open signatures are hung over a chain or “saddle.”
  •     The signatures may then be transferred to succeeding feeding stations. This is howsaddle stitched signatures are inserted into each other.
  •     Covers are scored and folded on the saddle stitching machine. Then they are laidon top of the signature[s].
  •     The product is stitched through the fold, trimmed on three sides.

What are the limitations to printing on the spine of a perfect bound cover? On a double loop book with a concealing cover?

On a perfect bound or double loop cover, you may print the entire area of thespine, but be sure to consult with us beforehand. You’ll need to measure the spine using a bulking dummy to be sure of the exact width. Ink coverage that traps to scoresor bleeds across the spine will also need close attention to ensure proper registrationand to avoid cracking. In addition, perfect bound books will need four scores on the cover [two backbone plus two hinge] for durability and to protect any glued areas when opening. The paper you choose is also a consideration for perfect boundbooks; text and cover pages must be parallel with the spine or the covers may wrinkle.

Which binding techniques are best suited for short runs?

Common binding techniques, like saddle stitching, loop stitching and side stitching are the simplest – and most economical – choices for short runs.
