What is Digital Printing

You may not realize all this is very familiar with digital printing. Office everyday and you always use it at home. Digital printing is all reproductive technologies that receive electronic data and use the point (dot) for replication. All the printing press that utilizes the computer as a source of data and the print process is using the principle of the point; where the picture or image in materials (paper, plastics, textiles, etc.) are composed of a collection of points. Definition printer, copier, press
Based on the print engine existing applications, the digital print classified roughly 3;
(1) printer - such as a printer for the Personal Computer (PC)
(2) copier - such as copiers equipped with a scanner
(3) press - such as offset printing machines.

Printer is all the technology, which makes printing pictures or images on paper drawn from the data / computer files; produce the first derivative of the print or original printing in which each mold can be unique or changed. This feature provides the ability personalized printed materials. All documents can be an individual. Ink technology can be used inkjet, wax-transfer and toner.

Copier or a copier, scanner tool is characterized by; produce a second derivative mold. Copiers can reproduce the first derivative of the mold. Common ink toner used is, using technology elektrofotografi.

Press or printing press, characterized by a mechanical system that relies on conducting (carrier) image to replicate or duplicate an image similar to the material (paper) printed repeatedly and continuously. Commonly found in lithografi offset printing equipment, which allows to print the paper size and bulk.

In the development of digital printing applications, from the three groups developing mixtures machine;
1. Printer Press
2. Press Printer
3. Scanner Printer.

Printer Press, often referred to as a printer print (the first derivatives of documents) good high quality black and white or color. Printer engine speed reaches 50 pages per minute or more, which is equipped with a belt to speed up "delivery" and holding a paper with a static electric effect. Replace belt roller which often cause problems for high-speed jamming. This tool enables the printer to make a dynamic image / changed on the photoconductor belt or a drum for every 50 pages printed. Not infrequently this printer device equipped with a bindery and finishing facilities.

Press printer, printing equipment offset press with the process of conducting a direct image above offset machine - without any outside prepress process of printing, the printing device is added to the printer at the end to provide a dynamic / changing. Usually a set of printing these additional printers using inkjet ink technology.

Printer scanner, printer, printing device equipped with a scanner equipment. This printing machine is equipped network-related RIP, raster image processor, allowing to modify the results of the scanning image. This type of information is the first derivative of the document, is different from the copier machine is often confused because both use the equipment scanner.Reproduksi Information
To better understand the concept of digital printing, so there are roughly 2 reproductive groups of information;
1. Static printing
2. Dynamic Printing.

Static Printing, the process of doubling the same information and remain in large numbers. To change the information from one printout to spend effort, cost and a large amount of mold that are not needed. We refer to the traditional print processes such as offset printing machine, where the image carrier is blanket contains the same information and keep for a number of sheets printed.

Dynamic Printing, the process of doubling the information that could change for each sheet printed. We can refer to the copier machine or copier, which can multiply each sheet of paper with different information depending on the information you want copied.

Based on the characteristics and general nature of the dynamic printing above were found on equipment, methods and digital printing technology. Ability to provide dynamic information associated with the use of files and / or the computer itself. Computers are the main pillars of digital information printing.Parameter Reproduction
Broadly speaking there are 2 groups of parameters;
- The main parameters and
- Parameters complement to distinguish Static and Dynamic Printing, and at the same time the guidelines in using each type of mold.

The main parameters, parameters that are unique and specific in distinguishing static and dynamic printing, consisting of;
1. Image carrier
2. Variability information
3. Cycle time
4. Number printed
5. Front cost
Further explanation can be seen following paragraphs "Defining Digital Printing".

Complementary parameters, parameters that nature continue to grow and change as possible in which a lack of means and the unique differences between static and dynamic printing, consisting of;
1. Quality printing
2. Type of paper
3. Demy
4. Ink materials
Further explanation in the paragraph "Technology Equipment Digital Printing". Defining the Digital Printing
By understanding the parameters above we easily see and define the multi-aspect and the name of digital printing. Dynamic printing itself is a red thread of the term digital printing, where the use of computers and computer files is the origin of the development of digital printing.

Technological developments of the main parameters of reproduction of information leading to the development of digital printing aspects, among others;

1. Direct Imaging;
Associated with the process of making "image carrier" (such as pengahantar image plate and blanket)

2. Variable Printing
Associated with variable information

3. On-Demand Printing
Related to the amount of mold, cycle time and cost front

4. Distributed Printing
Related to the technology itself, computer files that can be moved and stored

5. Digital prepress and Workflow
Related to the technology itself, computer files that can be moved and disimpanImpact & Non-Impact Printing
Are factors and non-impact printing has impatc and role in the development of digital printing?. The answer is yes and no, at first all digital printing refers to the non-impact printing wlaupun with direct imaging technology we can do process printing lithografi the impact printing.

However, this term is clearly not a factor that defines digital printing.
Impact Printing, with the ignition ditandadi image carrier with printed materials (paper, plastic). Technology Equipment Digital Printing
The development of digital printing equipment technology is strongly influenced by the use of ink materials, among others;
- Ink
- Toner
- Inkjet
- Other

Print quality, paper and size is influenced by technological developments affecting the above and at the same time the print market segments that exist.

Using Ink in Digital Printing

In general, the ink used for digital plotter machines are divided into two types namely: water-based inks and solvent-based inks.

Water-based inks there are two types of ink, dye and pigment ink. Dye ink provides color printout is perfect but have a short survival when used for outdoor (outdoor). Pigment ink has a color printout is pretty good (not as good as dye ink) and have good endurance, for in the room survived for hundreds of years while outside the room could hold up to 4 years with the help of laminate. In general, the second ink on the media used to have in-coated (which generally has a high price).

Mild solvent gives color printout is perfect, and can be used on coated and uncoated media media. Mild solvents are generally able to survive beyond 3 years in space and can survive up to 5 years outdoors with the help of laminate. Mild solvents are environmentally friendly because it does not smell so do not require special ventilation in the process of its use.

Solvent ink / Standard Solvent excellent media used for uncoated and has a very good power to outer space (outdoor). However, this raises the ink very stinging smell that require special ventilation in the process of its use.

In addition to the above type of ink is also known another type of ink sublimation ink (Heat transfer inks). This ink generally enter into the category of water-based inks, the ink is used for digital printing processes such as t-shirts, mugs, plates, ceramics, and so on.
