DIGITAL PRINTING

Digital Printing
Digital technology into all areas, including in the print world with the emergence of Digital Printing. This technology provides easy to print as needed. Digital Printing Will it take the offset printing market.

In the definition say that the Digital Printing is "Any Printing completed via digital files".

Digital Printing is a printing technology without going through the process of making the print form, such as printing plates or printing cylinders.
In Jakarta, many service companies in the Digital Printing and it can have large format inkjet printers for Indoor or Outdoor, there is also a Xerox machine or Indigo or Konika or even photocopy services and a digital output of A3 + size.
Digital Printing an alternative printing processes, which are currently "booming" in Indonesia.

Types of Digital Print

Some digital print systems include:
1. Direct Imaging System
2. Electrophotography System

Direct Imaging 1.Sistem
Direct Imaging is a process that uses light (laser beams) for making a digital image directly on printing plates after the printing process is done. Printing plates used were conventional plate is permanent, to 1 representing 1 color plate. Direct Imaging System is a combination of technologies CTP (Computer to Plate) with conventional offset printing technology.

2.Sistem Electrophotography
Electrophotography is a process that uses light to discharge (taking charge) electrically area in-charge (given an electric charge) that produce latent image (hidden image) that can be developed (raised) by the ink.

Examples of machines that use Electrophotography technology is:
- Ink Base (liquid ink-based) such as HP Indigo
- Toner Base (based toner powder) such as Canon IRC3200, Oce Digital Printing
- Docucolor 2045/2060, xeikon

Judging from the current function can be grouped in 4 groups of needs, namely:
1. Needs "Print On Demand"
2. The need for color proofing (digital color proofing)
3. The need posters in the room (indoor)
4. The need for outdoor posters (outdoor)

1.Kebutuhan Print On Demand (POD)
Digital Printing Advantages
1.Short run priting
Print with a circulation of under 1000 in full color printing including 3 sheets, 20 sheets, or 100 sheets.

2.On demand printing
Scored according to the needs, anytime, anywhere and can update or change information as it prepared to print. Print one sheet or 100 sheets can be with the same relative prices. In Jakarta in 2005, the price of digital printing to A3 size on average USD 25,000.00 to USD 30,000.00 per share until 5 sheets.

3.Personalization
Have the ability to print a personal or perindividu or pergroup with varying data. We can make special designs for one person to keep good quality and fast time and others may not accept it.


4.Distributed printing
Digital can be directly printed simultaneously in other places, immediately after the data is accepted everywhere.

Digital Printing Machine for the needs of on demand is designed as efficiently as possible to the production of small amounts of circulation, about 10 to 1000 exp. But the current development of Print On Demand has changed rapidly since driven the digital trend in all sectors.
On Demand Printing provides advantages and disadvantages when compared with offset printing.

Benefits On Demand Printing:
1. The process is much faster
2. Does not require separation film or printing plates, so cutting costs.
3. Appropriate amount; On demand printing to print only the desired result.
4. Preparation time shorter
5. Production costs are cheaper for a small circulation.
6. Personalization; print digitally controlled by a database so that images can be modified according to individual tastes.

Losses On Demand Printing:
1.Biaya per unit cost when printing in large quantities.
2.Keterbatasan the use of paper.

2. Digital Color Proofing Needs (DCP)
Needs in this segment is a color proofing results can be controlled and adjusted or simulated with the target color printing such as offset printing or a label, and Rotogravure.

Print Digital Color Proofing is not as easy as other printing needs, this process needs color adjustment, in which the printing should be similar to the desired target color.

In this process other than the usual inkjet printers used, also needs an additional software RIP software which these devices have the ability to perform color management is to convert the color and control the amount of ink out of the inkjet printer according to the expected target.

Use wide inkjet printer (up to 40 inch) allows for printing with a large printing press to control the position and layout (form proof), therefore reducing errors and imposisi layout.

Excess Digital Color Proofing
1.Kemampuan to reprint
Proofing to ensure the same results from the same digital files each time. Consistency of color and color stability is required in order to be used as a guide when calibrated color.

2.Simulasi dot gain curve
The highest dot gain value usually occurs middletone area. Digital proofing machine capable of simulating dot gain is very helpful in achieving color accuracy, especially for different types of paper.

3.Keakurasian Color
Accuracy in matching the target color, to select the target color range and then measure the actual difference is very significant deviation noted. This can use color management system.

4.Kecepatan
DCP engine speed is very influential to the kinds of jobs that require deadlines, such as in newspapers, advertising, publishing and others.

In 3.Kebutuhan Poster (Indoor)
The use of posters in the room (indoor) a lot done for promotion, there are 2 kinds of ink used is "Dye" and "Pigment". Ink "Dye" usually have brighter colors and is widely used in several types of inkjet printers, but not waterproof, while "Pigment" is resistant to water can be found on devices such as inkjet printers Roland DG wide or Epson and others.
We have machines with a width of more than 2.5 m for this indoor needs. Because the posters in the room will be enjoyed in a relatively close distance, then the resulting picture quality has a high enough resolution (up to 1440 dpi) and the use of additional ink colors such as Orange, Green, Photo Black and others, to improve the quality of the resulting color (expanded color space or color gamut reproduction). In addition to the above brands following are the types of inkjet printers which represent the needs of the posters in the room, for example: Cannon, Encad, Epson, and Hewllet-Packard, Mutoh.

Foreign Poster 4.Kebutuhan (Outdoor)
The use of outdoor posters (outdoor) are usually identical to the print ultra-wide (more than 1.5 meters), therefore the machines also offer a very wide, even reaching 5.3 meters (Vutek). Another vendor that offers outdoor equipment for the needs of production, especially Asia (Japan, China, and Korea) is Mutoh, Roland DG, Infinity, Challenger, DGI, and some brand new arrivals will be making a poster in the world outside the room.
Because of the need to enjoy the outdoor distance and outside the room, the image resolution is usually not necessary too high (can be under 72 dpi), but the ink solvent is usually long lasting and printed materials must be very strong and flexible, so as to keep friction (scratch), wind, sun and rain. Width is very helpful poster size is very wide because the technology "Tambal atu seaming" quite expensive and need accuracy in positioning the mold and color reproduction, the second error it will make the poster look less beautiful. Resolution is used for large format posters (outdoor), as posted on billboards, buses and public places is very dependent on the observer visibility. To get the resolution different, let alone any type of material is very varied.
