Finishing Processes
 

Finishing Processes as far as print is concerned is a general term that is used to describe the processes that are taken after a project has been printed. Such processes include laminating, mounting, coating, image transfer, and trimming. These processes are sometimes referred to as a value-adding process.

Printing Dummy


A printing dummy is what is commonly known as a proof. All the printing dummy is is a mock up of what the final print whenever assembled is suppose to look like.

Imagesetter
An imagesetter is a high-resolution output machine that can transfer electronic text and graphics directly unto film, plates, or a photosensitive paper. The imagesetter is pretty much a high res printer that, alike printers, can come in various sizes and formats. The imagesetter consists of a laser and a dedicated RIP and is compatible to create the film used in computer-based preproduction work.


Pica's vs. Points

Pica's and points are both measurement devices for type. 12 points is equal to 1 pica. Some people prefer to use pica's on document measurement rather than inches, but points are the universal suit for type sizes.

Die-Cutting
Die-cutting is a printing process that cuts your documents into certain shapes, the die-cutting machines can be purchased in various sizes for either industrial size jobs or small enough to use on individual projects. Much like a cookie cutter, the die cut is a blade that has been bent into a specified shape. After the die is put into the machine you then put in your medium and the die-cut will cut your medium into the desired shape of your project.

Purpose of a RIP

RIP stands for Raster Image Processor, the RIP is an output device that turns your vector based project into high res images that can be output. Such things as fonts and photos can translated into a work piece that the RIP can turn into small dots so that RIP can print your project accurately.
The RIP process is a huge part of a print project, as another piece of the puzzle to enable your project to turn out exactly how you want it and exactly how your customer wants the project to be. The RIP enables you to turn your designs into a printed reality.

VDP

Commonly used on such things as direct mailers, postcards, flyer's, notepads, promotional pieces, or anything else that you are wanting to speak directly to your customers the Variable Data Print is a huge piece of printing and self promotion. Variable data printing capitalizes on this by picking up customized artwork for each page based on information from your database and rules that are set up within the Variable Data software program. Variable elements can be text, graphics or photos, color or black-and-white. Variable data can be flowed into each page on a simple record-by-record basis, or the contents of a page can be controlled by sophisticated rules based on relationships among data fields.(Greenerprinter)

Two-color printing

Two color printing is exactly how is sounds your print produced by two colors of your choosing. Now due to common thought that your project that you design with three or four colors you can actually produced the same project using two colors. Projects can be produced with two colors simply because you can use two color prints to create shadows and bevels on the print. 

PPI, DPI, LPI

As in print the definition of DPI stands for dots per inch. The specific definition is this, a measure of the resolution of a printer is called DPI or dots per inch. It properly refers to the dots of ink or toner used by an imagesetter, laser printer, or other printing device to print your text and graphics. In general, the more dots, the better and sharper the image. DPI is printer resolution. (desktop)
As you read the specific definition, in print knowing what your dpi is a must, now it seems that for photography uses something called PPI, which stands for pixels per inch. Obviously within photos the camera saves your pictures with pixels therefore you need to know what your PPI is for printing purposes.
Now LPI was a tough one to really figure what it was used for, within being in commercial graphics I had heard a lot about PPI and DPI, but LPI was a total new concept for myself. LPI stands for lines per inch. As my research has found is that LPI is very commonly used for photography, which surprises me that I’ve never heard of it. LPI also comes down to what type of paper that you use and your printer that you are running off of.

CMYK vs. Color Spots

Being new into the realm of print I’d know that CMYK stands for Cyan, Magenta, Yellow, and blacK hence CMYK.  Now I’d never seen anything about color spots until looking at our first project and reviewing the preflight checklist that asked about the color used and I noticed color spot 1, and color spot 2.
Spot coloring uses the pantone system and involves either 1, 2, or 3 premixed color choices, also it is said to be a more accurate color choice because the colors are not being mixed during the print process.(Vision)
