 The CFPR's Research into nineteenth century, high quality printing processes
Due to the delicate nature of its printing substrate, collotype was used as a specialist process for the limited edition of the highest quality prints.
The print, a reproduction of a photograph by Camille De Silvy entitled Proclamation of the Army for Italy was printed by F. Jourbet, a French printer living in England.
As the artist's print came to be accepted as a new form of multiple original, its value within the art market also increased.

 Printing meets lithography: Soft approaches to high-resolution patterning
Screen or stencil printing [Figure 1(d)] transfers an image by passing ink through openings in a stencil that has been applied to a screen substrate.
Conformal contact comprises 1) the macroscopic adaptation to the overall shape of the substrate and 2) the microscopic adaptation of a soft polymer layer to a rough surface, leading to an intimate contact without voids (Figure 2).
During a printing step, an ink may be transferred to the substrate (additive print) or removed from the substrate (subtractive print), the chemical nature of the substrate may be altered in the zones of contact (convertive print), or the substrate itself may be selectively removed (etching).

 UV SOURCE PRINTING
With flame treating, plastic substrates are momentarily passed in front of a flame jet prior to being printed.
As UV screen printing becomes more and more popular, it is essential for the potential UV printer to have a clear understanding of how UV inks function and of how to select the correct ink for the particular substrate.
Now entering its third decade, UV has made and is continuing to make further inroads into the screen printing industry.

 ScreenWeb Get Production Rolling With Rotary Screen Printing
Screen printing is also associated with piece-decorating applications, in which individual sheets of substrate are printed one by one, usually on semi- and three-quarter-automatic flatbed presses that require manual loading and/or unloading.
On a flatbed press, printing is a two-step process that involves a pass over the screen by the floodbar to fill mesh openings with ink, followed by a squeegee pass to bring the stencil and substrate into contact for ink transfer.
They feature stencil rings that both support the cylindrical screen and allow it to be attached to the printing module.

Printing using a printing press dates back to the printing press article.

 Understanding and Using Pad Printing Inks
Another, less reliable test is to mark the substrate with a ball-point pen.
The ramiliar cross-hatch test, shown here on a cylindrical substrate, is the most common adhesion test in pad printing.
You then apply Scotch tape and remove it with a sharp pull at an acute angle to the surface.

 Screen Printing Process Measurements - Emulsion, stencil thickness, off-contact, and mesh
Sampling or periodic measurements of the substrate being printed ensure the off-contact distance is maintained.
General substrate thickness can be measured with an eddy current EOC probe by using the aluminum vacuum table/platen as the zero surface.
The thicker the mesh, the thicker the emulsion coating required to encapsulate the mesh and form a stencil with a smooth stencil surface (Rz-value).

 Substrate (printing) - Wikipedia, the free encyclopedia
Substrate is a term used in printing, mainly industrial printing, to describe the base material that images will be printed onto.
Because durability and longevity are not needed, a paper that has a low cost and low quality is chosen to be the substrate - newsprint.
These are some of the terms used to describe the qualities of substrates:

 Patent 4275656: Bubble printing method
Substrate 22 may be any of a number of various materials, such as woven, knitted, felted, or other textiles, elastomeric or polymeric materials, and the like, and should not be considered to be limited to any particular material.
After the array of bubbles 34 is formed on substrate 22 by generators 28, it is carried under the array of generators 29 by the motion of the substrate.
As the substrate passes wetting apparatus 26, it is sprayed with a solution of a wetting agent.

 Patent 4758952: Process for heat transfer printing

 Flexo Magazine - Inks: From Art To Science, Choice of Corrugated Substrate Determines Ink Ingredients
Inks: From Art To Science, Choice of Corrugated Substrate Determines Ink Ingredients
When printing is done on clay-coated board, poor coverage or poor trapping is often the result of poor adhesion to the substrate, due to the materials in the ink having a combined surface tension that is higher than that of the substrate.
This produces a cohesive effect (opposite of adhesive), causing inks to shy away from certain areas of the substrate and resulting in an uneven appearance on the final print.

 Lithography beyond light: Microcontact printing with monolayer resists
Microcontact printing works equally well on spherical substrates (such as optical fibers or lenses), even where these substrates have radii of curvatures less than 10 µm [9].
A network of openings between a stamp and a solid substrate, filled with a liquid prepolymer by capillary action, provided a template for the structure resulting from polymerization of this liquid.
First, pattern transfer is effected directly on contact by a molecular-scale interaction between the stamp and substrate, resulting in a highly controllable chemical modification of the substrate.

 Printing Process Descriptions: Environment and Printing: The Printers' national Environmental Assistance Center: PNEAC: The Environmental Information Website for the Printing Industry
The image is printed as substrate is pulled through a series of stations, or print units.
After printing, the substrate may run through a number of operations to be "finished" and ready for shipment to the customer.
The inks are formulated to lie on the surface of nonabsorbent substrates and solidify when solvents are removed.

 Substrate Noise in Mixed-Signal ICs - Presentations
In the latter case, prior to analysis of the substrate effects through either simulation or using pattern-independent approaches, an appropriate resistance model for the substrate must be extracted.
Generation of digital disturbance, propagation through the substrate and effects on analog devices are considered, with a particular emphasis on integrated circuits realized on heavily-doped substrate, where traditional shielding is less effective.
Coupling this high-level model with the model of the substrate noise injection of the digital part will reduce significantly the simulation time needed to make the analysis, and the only limitation will be the substrate noise model extraction.

 Enzymes, Kinetics and Diagnostic Use
At lower substrate concentrations, such as at points A and B, the lower reaction velocities indicate that at any moment only a portion of the enzyme molecules are bound to the substrate.
As enzymes have a more or less broad range of substrate specificity, it follows that a given substrate may be acted on by a number of different enzymes, each of which uses the same substrate(s) and produces the same product(s).
At substrate concentrations near point A the rate appears to be directly proportional to substrate concentration, and the reaction rate is said to be first order.
