Artist Proof (AP)- Often numbered, these copies of a

limited edition print are signed and typically titled "Artist

Proof." Artist proofs originally were the first copies printed

and were used to indicate the artist's approval of color

reproduction and other mechanical aspects of the printing

process. Once prized as best quality copies (see

Lithography), artist proofs now exist solely as part of the

printmaking tradition and are of a quality similar to the

standard edition print. Artist's proofs are distinguished by

the abbreviation AP and are numbered separately. They

often represent 10 percent of an edition and are slightly

more expensive than prints in the regular edition.

Cancellation Proof - Final print made once an edition

series has been finished to show that the plate has been

marred/mutilated by the artist, and will never be used again

to make more prints of the edition.

Canvas Print - A reproduction in which an image is printed

directly onto canvas. These prints can be produced using

offset lithography, digital printing or other methods.

Sometimes artists will add brush strokes directly onto the

canvas after the piece has been printed.

Canvas Transfer - A reproduction in which inks are

chemically lifted off a piece of paper and applied to a piece

of canvas. Some processes can replicate the texture and

appearance of an original painting.

Certificate of Authenticity - A warranty card or statement

of authenticity of a limited edition print that records the title

of the work, the artist's name, the edition size and the print's

number within the edition, the number of artist's proofs and

the release date. It is a guarantee that the edition is limited

and that the image will not be published again in the same

form.
