Flat - in photography, characteristic of an image that lacks contrast. In printing, an assembly of negatives taped to masking material and ready for platemaking.
Flex die - This die type is an outgrowth of steel rule. However, it utilizes the making processes of forged dies and, in conjunction with modern hydraulic presses, is taking over much of the work done previously only by forged dies. Diemakers can attain a good degree of skill within a short time. The basic die material is totally prefinished and needs only bending and welding to finished form. This die type is known also as swedish die, light-weight die and cutting rule die. Many of the misnomers attached to forged dies are also attached to the type.
Flex die steel - Pre-sharpened edge hardened die steel that can be cold formed. Generally 6-8 point thickness.
Flexographic printing - Printing from a raised surface, generally rubber plates. Limited to line, solid, or Ben Day printing. Rotary type printing using a very fluid solvent or aqua ink. This was formerly called the aniline process.
Flexography - A method of direct rotary printing using resilient raised image printing plates, affixed to variable repeat plate cylinders, inked by a roll or doctor-blade-wiped engraved metal roll, carrying fluid or paste-type inks to virtually any substrate.
