Printing Technology Q&A (7-14)

7, Q: The general inkjet size is very large, then set the image size in ps when the setting is much better? How big is it to be sprayed? What the monitor sees! Is it 10:1? Also? Do you have to use CMYK for inkjet printing, isn't it better to use RGB if it is a printer?
A: This mainly depends on whether you are doing a photo or inkjet. It is generally the original large size. The resolution is 100 DPI. Printing is generally the original large-size resolution of 35dpi. You don't have to use RGB graphics, but when you're doing the map, you have to turn on the overflow warning. Of course, it's better if you use outdoor inkjet or RGB mode, because the inkjet printer uses ink instead of printing. Ink, its color hiding is not as strong as printing. If it is a photo machine, its size is preferably the original size, and the resolution is about 100dpi. Of course, the higher the better. The HP5000 format is about 1.25 meters.

8, Q: If you paint a dozen or dozens of square meters, as set in the ps in the original big, then the 17-19 monitor see so much? I think a little unbelievable?

A: This should be flexible. If that is the case, you should make it 1/10 or 1/5 of the original size. Is it ethical for us all to do? Try to give the customer some clarity. In short, the size of the file is generally maintained at about 50M to 100M (the resolution is maintained at 100ppi to 50ppi), and the size is large, the resolution is reduced, and vice versa. Be flexible! The normal dpi of the inkjet is 72dpi, some people say it is a golden dot, and then according to the figure, the dpi is generally set as the dpi is lower, but for the effect of the picture, the minimum is not less than 35dpi. The smaller the picture, the dpi is. High, especially with very little text. But the highest is not higher than 300dpi, thumb, 300dpi will not affect the speed of the computer, but enough

9. Question: Where should I open to ask for an overflow warning?

Answer: There is always a color gamut on each machine. If it exceeds this color gamut, it will overflow. For example, the general photo machine K100 is always dark gray.

10. Q: What is a photo?

A: The small-format indoor inkjet, such as the above-mentioned HP5000 is a photo machine, and its width is 1.5M, six color ink head. The outdoor inkjet has 3-8m face width.
The printing accuracy is generally 100dip/inch, and the printing is 300dip/inch.

11, Q: inkjet printer can be sprayed without borders to it? It's like a ten-meter-wide outdoor ad.
A: This is to connect, is to put a few pieces of cloth together, then the hard-to-find
12, Q: What is a photo? What is silver eagle paper? Are photo and silver photographic papers and inkjets different concepts? Does the photo really mean if you want to make oil paintings? Can the lamp be glued on the back? Is the photo clearer than the lamp, in the same state?

A: High-definition inkjet is a photo, refers to the inkjet printing accuracy of 300DPI / inch (and the concept of the same printer) above the inkjet photo, such as photo paper inkjet, general indoor inkjet are photo.
"Silver stencil paper" is like a silver inkjet photographic paper. The effect of inkjet printing is like four-color inkjet printing on a silver spot color. This photographic paper is relatively thin.

The feeling of oil painting can be sprayed with canvas cloth (now inkjet printers can spray canvas).
The back of the lamp is not glued to increase its transparency. It can be clamped with plexiglass before and after, and lighted with a lamp at the back. Acoustic lights are also photo-realistic, with the same clarity. (Some of the lights are silk screened, and the accuracy is also very high, but it's not a photo, the photo is in the inkjet)

13, Q: When I am printing, I do C0M0YOK100 in CD, inkjet company wants me to use C60M50Y60K100? Everyone is black. Why is it different?

A: This is because the black jets of inkjet printers generally have less ink, and the ink can easily block the nozzles. In order to not affect the effect, the inkjet company uses other colors to form black, so that the black part does not return to obvious roads. If the inkjet printer is a new nozzle, you don't need this setup. This is the characteristic of the black solute in black ink. The world has not yet solved this problem.

14, Q: What is adhesive, what internal light, external light?

A: The back is covered with plastic film, like a self-adhesive; inside and outside the light, I do not know is not the same as the name is not the same everywhere; called matt film and film here, is the surface of the film is not the same as the media . The light inside and outside is used for the light cloth. The light cloth used inside the light box is called the light cloth inside. An opaque light cloth that uses a rack lamp to light from the outside is an interior light cloth. Extra-large inkjets are external light cloths, and small light boxes use internal light cloths.
