A substance used for sticking objects or materials together (glue). At SheetLabels.com we have labels with general-purpose permanent adhesives, a label material with a high-tack permanent adhesive and labels with a removable adhesive.
  • Permanent Adhesive - Labels that do not remove from surfaces with ease. These are meant for long time use.
  • Removable Adhesive - Type of adhesive that allows you to adhere and remove labels from most all surfaces with ease.
 

AI

 
The .ai filename extension is a proprietary file format developed by Adobe Systems used by Adobe Illustrator.
 

BLEED

 
Printing that extends to the very edge of a sheet after it is trimmed at the crop marks.
 

CMYK (cyan-magenta-yellow-black)

 
The color model in which all colors are made as a mixture of these 4 colors. This color model is used in offset printing.
 

CONSTRUCTION

 
The actual makeup of the face, adhesive, and liner of your labels
  • Face – Top portion of the sheet (Actual label and adhesive backing)
  • Liner – Backing of your label construction
 

CROP MARKS (also known as REGISTRATION MARKS)

 
Lines printed on the margin of a sheet that indicate to the printer/bindery where the finished product should be trimmed.
 

CURL

 
When your sheets of labels are distorted and will not lie flat due to changing temperature or humidity.
 
Please see this video for help working the curl out of your labels.
 

CUSTOM TOOLING

 
Customized die that is made specifically for your unique size labels.
 
If you cannot find the size label you’re looking for, we offer custom sizes for our customers.
 

DIE

 
Tool for cutting and scoring label stock, paper products, and more.
 

DIE-CUT

 
The process of cutting and scoring label stock, paper products, and more.
 

DIGITAL PROOFING

 
Page proofs that are sent and reviewed electronically to ensure that the artwork is set up exactly as customer requests.
 
These must be approved by customer before any printing will be done.
 

Dots Per Inch (DPI)

 
A measurement of resolution of input, output, and display devices.
  • DPI measures how many dots fit into a linear inch
  • Our required printing resolution is 300 DPI

EPS

 
EPS files are self-contained PostScript documents that describe an image or drawing and can be placed in another PostScript document. EPS stands for Encapsulated PostScript.
 

FROSTY CLEAR

 
Frosty clear labels have a cloudy, matte appearance. Not a crystal clear appearance.
 

FULL BLEED

 
Text or graphic that extends all the way to the edge of the paper it is printed on. After trimming, the bleed ensures that no unprinted edges occur in the final trimmed document.
 

GLOSS

 
A coating on labels/paper that provide a higher reflection of light which creates a shiny appearance. The gloss label coating can reduce ink absorption which gives the printed product much better contrast and color definition.
 

GSM RATING (also known as PAPER DENSITY or PAPER WEIGHT)

 
GSM is Grams per Square Meter. This denotes the thickness and weight of the material. Certain printers have a maximum GSM rating, which is the thickest material the printer can handle.
 

HALFTONE

 
A continuous tone image that has been scanned and converted into tiny dots that vary in size to create a variation in tone. Light areas have small dots and the darker areas have larger dots. This is how printing various shades of grey is possible with black ink.

The distance between the columns of labels on a die cut sheet
 

INDIVIDUAL CUT-DOWN LABELS

 
We offer printed cut-down labels. These labels are shipped as individual labels and all cut-down labels have square corners.
 

INK ABSORBENCY

 
The attribute of paper that determines the quantity of ink penetrating the paper and the rate at which it is soaked up after contact with.

  • Slit Over Perf – A slit in the face of the material right above a perforation in the liner of the material
