The weight, in pounds, of a ream (500 sheets) of paper cut to the "basic" size. Also called ream weight and substance weight (sub weight). A common example is 20# copy paper.  The "basic size" of that sheet is 17" x 22" and 500 sheets weighs 20 lbs.

The  department within a printing company responsible for collating, folding, trimming and binding various printing projects.

A press blanked is a rubber-coated pad, mounted on a cylinder of an offset press, that receives the inked image from the plate and transfers it to the surface to be printed.

Printing that extends to the edge of a sheet or page after trimming.  You can read more about bleed and trim on our blog.

A page number that is not printed on the page. For example in a book the first few pages in a book often do not have page numbers.  Those are blind folios.

A blind image is an  that is debossed, embossed or stamped, but not printed with ink or foil.

Blocking or bricking is when printed sheets stick together.  With offset presses this happens if there is not enough anti-offset powder on the sheet.  With digital printing this can happen if the pages are not cooled adequately before stacking.

Blueline proofs are photographic proofs made from stripped negatives where all colors show as blue images on white paper. Because 'blueline' is a generic term for proofs made from a variety of materials having identical purposes and similar appearances, it may also be called a blackprint, blue, blueprint, brownline, brownprint, diazo, dyeline, ozalid, or position proof.  This term is outdated and really shouldn't be used any more.

Board paper or board stock is a general term for paper over 110# index, 80# cover or 200 gsm.  It is comonly used for pocket folders, packaging, displays, and hardcover books.  It is also sometimes called paperboard.

Bond paper is a category of paper commonly used for writing, printing and photocopying. It is an uncoated paper that absorbs most kinds of ink.  It is also called business paper, communication paper, correspondence paper and writing paper.

Book paper is a category of paper suitable for books, magazines, catalogs, advertising and general printing needs. Book paper is divided into uncoated paper (also called offset paper), coated paper (also called art paper, enamel paper, gloss paper and slick paper) and text paper.

Bounce is a repeating registration problem in the printing stage of production.  In other words the image is "bouncing" around on the sheet and not printing in the same place on every page.  It is possible to have only one color bounce.

Building a color is the process of overlaping two or more screen tints to create a new color. Such an overlap is called a build, color build, stacked screen build or tint build.  Almost all colors in a traditional printing process are built using a combination of Cyan, Magenta, Yellow and Black.

Butt registration is there ink colors meet precicely without overlapping of allowing space in between.  In other words they butt up against each other.  Most printing allows colors to overlap or trap very slightly so as to not show tiny imperfections of misaligned registration that would be visible with butt registration.

A buyout is a service that is subcontracted to an outside vendory. It can also be called a farm out.  This is often done for a small specialty part of a job that we may not have the equiptment to do in house.
