 The large version is a pre-press subject with its own information. In theory it is simple. But in fact, it is quite complicated, and the big version is a bit like the Blu-ray dance step - five minutes to learn for life.

The marker map is the smallest component of the layout layer. Many tag maps produce layouts. Each marker map consists of the front and back of the sheet. The prints of multiple pages that can be printed on a single sheet of paper constitute a number of indicia. Before you create a marker map and do the imposition work, only a few sheets of parameters need to be determined.

· What type of binding will be used?

· How will the second side of the printed sheet be printed?

· How large is the paper size?

· How will the folds be printed?

Interestingly, even some skilled professionals can't tell the difference between double-sided printing on offset presses. For this reason, we will make a brief explanation here.

Double-sided printing

Most of the printed sheets are printed on both sides of the printed sheet. Double-sided printing is one way. Double-sided printing requires a multi-unit printing unit with a device between the printing units. This facility can pull the printed sheet to the other side while allowing the remaining units to print the second side. This facility, which allows the sheet to be flipped, is called a perfecting press.

Another way to print the second side is by processing the sheets. This means printing the other side after the first print. The printer* author took the printed sheets back for printing on the other side, re-coded the paper, and started printing again.

Both (printing) methods require that the distribution of the pages on the film be in the correct order so that when the paper is unplugged, the correct printed sheet is printed on the back. Not only do pages have to be in the correct order, they must also be concentrated for the back. The parameters used for the layout are dependent on the press, the binding method, or the parameters of the printer.

There are three ways to enlarge: self-turning, rollover and front and back printing. The difference is how the printed sheets are processed after the first side of the printed sheet is printed.

Self-turning

The self-turning method is to print both sides of the printed sheet with the same plate. The first side is flipped after printing and the gripper remains stationary. This means that when on the second side, the paper jam caught by the printer is the same as the first side.

Roll over

Rolling is similar to self-turning, except that the first side of the printed sheet is printed, the paper does not flip, but rolls. This means that the paper is not on the same side of the paper.

Positive and negative printing

Pros and cons printing means printing the second side of the page with a different plate. For the front and back layout, you need two separate versions - one for each side.

Correct appearance

Bleeding. Many print providers have different bleeding requirements. Controlling bleeding is so important that you can rely on specific printing requirements to change the number of impressions.

Binding method. The app supports wireless binding, saddle stitching and other common binding methods.

User-defined margins and ordering. When the correct reading of a book or document is restricted, the gap between the two pages must be defined. Adding these blanks helps to accommodate things like crawling. Plate layout such as bottleneck state and placement of sporadic leaflets on the marker map.

Climb. The creep change is based on the paper thickness. It is possible that each job has different crawling characteristics. * Authors can type paper to have the app automatically adjust.

Bottle type status. The bottle status means that the paper is not square after being folded. The bottle type state changes depending on the folding mode and the binding method. Make sure the application allows different changes to be entered to achieve the minimum bottle status.

Efficiency consideration

Process OPI and DCS files. Spelling color files requires huge storage capacity and computing power. Each page (capacity) can reach up to 60MB, and an octal imposition can easily be as high as 0.5GB. Using OPI and DCS files can make imposition more quickly, because the application does not require copying all data, just for the placement of OPI files.

Imaging performance. When the color print is electronic, the program must be able to fully control the way the page is output. There are many properties that can be utilized depending on the printing method. For ease of naming, the film may be positive or negative, with the emulsion on the upper or lower layer. The ability to select different development and screen lines and color separation support is also necessary.

Printed mark. The placement and calibration of the printed mark should be user-defined. Some templates include printed indicia pre-set on the indicia. Although the use of printed indicia is useful, a good imposition software signboard is that it allows the *author to move the mark to where the particular press is most in need of the mark. Not all printed marks are equivalent, and not all printers prefer to use pre-defined print marks. It is important that print production personnel have the ability to create their own logo and apply it in the program.

Control tightening. Many presses have different types of clamping plates that cling to the rollers. Because of this difference, *author control is required from the edge of the plate to the edge of the sheet.

Electronic viewing platform. This facility allows the manufacturer to check on the display whether the back side of the paper is suitable for printing. It reduces the amount of damage. It is also important for computer-to-plate systems because no one wants the press to be a proofing system.

The template platform is changeable. Many imposition software is available on both Mac and personal computers. Many prepress companies not only have one computer dedicated to imposition. In a complex platform environment, it is important that the created templates are delivered to another platform without loss of functionality.

Some of these performances or defaults are important in determining which software to choose for your workflow. Another procedural feature may be interesting, but it may not be trivial to your business. Widths like interactive interfaces, programs found in workflows, and final products are rarely considered.

No matter how you look at it, the ability to spell an electronic document is the last obstacle to running large format output devices and digital presses. Now that we have this technology, it will be an important triad: presses, imposition software applications and output facilities.
