Screen printing lexicon
Screen printing (from latin sericum silk and Greek graphein to write) is a printing technique that uses stencils (originally silk screens) interposed between the ink and the support. The media used may be varied and not necessarily plans (pvc, polycarbonate, polyester, polypropylene, textile, metal, glass, wood, cardboard, paper etc.).
Prepress includes all operations that precede printing a document. These various operations are to put on the page and assemble graphic documents in order to produce films that will be shots on silk screens. Digital files are then sent to an imagesetter to film (CtF), or directly to the printer to digital prints.
The plate :
Download, operation by which one makes a cliché for reproduction. The film produced by the prepress Department is placed and insolated on the screen or printing form to reproduce the shape desired by our customers.
Silkscreen called « flattened » :
The so-called “flattened” silkscreen, refers to the type of machine used. Flat-bed screen printing machines are often automatic ¾ that print of the sheet to sheet. In the majority of cases and the Flat-bed screen printing machines, a passage equals a color, so as many color passing through.
The highlight : the great variety of possible support to printing and the ability to work medium quantities or larger quantities.
The weak point : lower rate of execution due to its mode of operation.
Silkscreen called « cylinder » :
The so-called “cylinder” screen printing refers to the type of machine used. The printing cylinder machines are always automatic machines. There are 2 versions, in sheet to sheet and roll. As for the flat-bed screen printing machines, cylinder machines more often have a passage for a color.
The highlight: making large volumes with a multiplied rate.
The weak point: the print size and the type of limited support as well as the minimum volume to be produced that remains high enough.
Silkscreen called « continued » or « Roll to Roll » :
The so-called “Roll to Roll” silkscreen, refers to the type of machine used. Most often used for the label, continuous printing machines are still working in automatic and in rolls. These machines are built so as to have only one passage for several colors. Most often between 3 and 5 positions of impressions. Finishing and shaping are done online and at the same time as printing.
The highlight: the rate of printing and the fact of being able to make very large volumes.
The weak point: its length, resulting in an important material waste, the printing format and the type of material very limited. But also, the fact of being able to do only very strong volumes.
The shaping is a term used in printing, screen printing, carpentry and bakery. It is a term that refers to formatting in a general sense. The shaping for the silkscreen or printing is the final stage of production before packing. This step is the finishing by cutting or shaping printed products.
Shaping said « right angle » :
The so-called "right angle" shaping refers to the shape given to the final product as well as the machine used for this step.
The machine used for this step is a cutter. You can imagine this machine as a big paper shears.
As the machine has only one straight blade, the only possible cut is inevitably right angle, to deliver rectangular or square products to the dimensions desired by our customers.
Shaping said « in shape » :
Shaped cutting can be done in 2 different ways, by mechanical press or digital cutting table.
- By mechanical press, cutting is done by pressure of the cutting tool support wood or methacrylate with sharp titanium blades. It is with this tool that we get the desired shape of the visual. The shapes must remain simple or coarse.
The highlight: the pace of execution and the possible large number of material.
The weak point: the limit of the formats to be cut as forms to produce.
By digital cutting table, cutting is done in "kisscut". A small computer-controlled cutter with a digital program cuts your material with a high precision. We use this type of cutting for lettering or complex shapes.
The highlight: form and finesse of cutting very varied and automation of the job.
The weak point: lower cutting rate than on a mechanical press and more limited material.
