Art rubber stamp processed info.

Sample A - arrow pin points a semi straight upright side bridge wall of about 90 degree angle from the stamp die floor base to the top character base rim.To accomplish this type
of finished die product that represents a mirror image of an artwork, a customer needs to provide a well executed art design sheet of print. A rubber die reproduction sample shown on picture on the right shows close vitrual duplicated transformation processed done from an actual well defined sketch artwork that's identically sharp.
Why is this important? Even rubber die of this class mounted on wooden mount stamp
given the hardest stamp pressure on a mounted stamp on any substrate can release
a clear print image impression without due swelling on rubber or rubber die expanding
that can cause poor print clarity. Nothing could replicate better die mold from art sketch
with tone values & edges in art that are clear and sharp.You may observe from sample
C as well from a side perspective view of a die that ink buildup cannot add a factor for
lesser quality print

Sample B-Consider an artwork printed on a piece of paper with solid bold object
lines but not so completely solid from its rendition and consider too if line edges of
each art piece are blurry,dull or not sharp. Relief/slope bridge then from a finished
rubber die would be wider or have a wider slant side wall as seen on sample D
and picture on right on a finished product. Defining artline sketch and processed
mandates one basic rule, allowing no hi-lites and freehand style fading end lines
stroke. **see note below** Furthermore,
remember there are no in-betweens and artwork must be provided with a simple
solid black tone line print even right down to the finest stroke in complete contrast.
Why is this important? Lets assume a text in words printed that you read seems
clear but yet unreadable but with the help of a magnifying glass everything else
are transpose in perfection.Transposing an artwork are similar in effect and also in process, in terms because of this irregularities then by a proceedure requiring over exposure, over baked, over curing to extract every problematic hard to read detail
lines and every problem tone values may help capture everything outline in the art piece just like what a magnifying glass would do, but however it confronts several issues as to the effect of relief measurements and its grade values. In simple terms when every thing done twice the amount of what should have been it devaluate the quality of the product but without which none or some hard to read lines may seemly disappear, fissure or be missing in the actual completed finished rubber stamp die it- self. This problem can arise and have a severe major cause resulting stamp print deficiency, from a shallow relief die base among other things! See sample D and B, a good example of what shallow relief has to offer! This type of die cast can create and cause unsatisfactory stamp impression print, allowing ink to collectively gather in between character spaces, pit holes and of characters releasing swelled print impression. Inked build-up from a shallow dept relief also prints bad.

To better understand - 4 basic steps in art rubber sheet production
a) Film, b) etched plate, c) board, d) rubber sheet.
film negative is the first basic step after artwork, it is a dark-room chemical process between your printed artwork and
a transparancy film. Film structures and determine how each proceeding step would play out after.

Etched plate is a photo chemically treated magnesium metal plate and requires contact light exposure using your film.
Again a darkroom chemical process requirement! This is the first of its mold process that ensures the quality of production
or evaluate the grade level standing that is the stage that tells a bad or good final final rubber sheet turn-out. Here it carries
down every element and outlines every single detail base on that artwork rendition from that film. However, in itself it is
now the primary medium as it would map the out come result of your rubber sheet as we said which determines the relief
height clarity factor and slope values. .
(Note- bad artwork / over expose three times the greater value = poor dept relief= wide blown slope)

Board is a type of fiber board, typical mold board that's cooked vulcanized against the etched plate making this the last transformation processed. Raw gum rubber do not interract well with magnesium plate that requires a special molding
board. The board is the final stage that serves as the master mold and repeatedly utilized each time a sheet of rubber is eminent or is needed to be press or bake.

POOR ARTWORK!
low poor sub-standard quality artwork means bad sub-standard rubber die sheets, it means shallow etched plate,
it means shallow relief rubber die from over cure, over exposure, possible cause to swell stamp prints or cause to
flood prints.

Two bearing factors (A & B) samples above draws about two dynamic out-come. A full sheet of artwork with a very good
artwork and one or two combined by a bad art piece can compromise and ruin the entire sheet of art rubber sheet. Design
pieces placed together and all done in the right way can produce high quality rubber die sheet.
