FAQ

There are two kinds :1.ready-made samples,could provide free samples for checking material,size and quality,you only need to pay delivery charge ;2.customized samples,if fully customized according to your request,you need to pay samples fee(usually about $310),cylinder fee(if there is printing ,one color one cylinder),mold fee(for bottom,holes and special shape) and freight charge.All these charge could be returned,it depends on the specific order quantity .

Up to 9 colors we can print ,means CMYK+white and 4 other special colors ,9 colors could meet 99% color printing requirements ,rarely have more than 9 colors ,and it will become very difficult if more 9 colors ,it's difficult to guarantee the quality of printing .Our printing technology is very good ,this is our a big advantage .

It depends on the size ,material and usage ,no way to fixed .Usually，the MOQ of bag (pouch) is 20,000 pcs,if the bag is very small ,such as 50*100mm or less ,need at least 100,000 to order .The MOQ of film is 200kg,if it's usage and requirements are very special ,you need to order 500 or 1000 kg .Of cause ,we can accept even lower than the quantity of MOQ ,but the price will be higher .

In the design of the system workflow is as follows: ① first press the final size of the image to scan the original, and in the image software to adjust the image, and can complete some creative design work.② in the graphics or typesetting software in the layout design work: including the input text, drawing graphics, into the image. ③ to be finalized, the document will be sent to the output center output film. Laser imagesetter is to use PostScript language, the RIP (raster image processor) to describe the layout of the dot-matrix image, and divided into C (cyan), M (magenta), Y (yellow), K (black) sheet. If the final requirements of the design is not output film, but a large color inkjet-like, then use the printer can output

Printing color is composed of different C, M, Y and K percentage of the color, so called mixed color is more reasonable. C, M, Y, K is commonly used in the printing of the four primary colors. In the printing of primary colors, these four colors have their own color version, the color version of the record of the color of the network, these outlets are generated by the halftone screen, the four color plates together to form a Defined primary colors. Adjust the color version of the dot size and spacing can form other primary colors. In fact, in the paper above the four printing colors are separated, but the phase is very close, because of our ability to distinguish the eyes have some restrictions, so do not tell. The visual impression we get is the blending of colors, producing a variety of primary colors. Y, M, C can be synthesized almost all colors, but also black, because the Y, M, C produced by the black is impure in the printing to be more pure black, and if Y, M, C to produce Black ink will appear too many local problems.

Color drawings or color photos, the number of colors on the screen there are thousands. It is almost impossible to print this thousands of colors in one color. Printing on the use of four-color printing method. That is, the first manuscript to color decomposition, divided into four-color version of CMYK, and then when the color printing synthesis. The so-called "separation" is based on the principle of subtraction, the use of red, green and blue filters on different wavelengths of shade with selective absorption characteristics, and the original decomposition of yellow, blue and green. In the separation process, the color filter is absorbed by the color filter itself is complementary light, as well as in the photographic film, the formation of black and white image of the negative, re-screening, constitute a network of negative, the final copy, tan into various colors Plate. This is the earliest photographic color separation principle.As the development of printing technology, we can now through the pre-press scanning equipment, the color of the original color separation, sampling and converted into digital information, that is, using the same method of photography with the original color is divided into three RGB color, and digital, The computer decomposes the digital information into CMYK four-color information through mathematical calculation.

Because the printing process determines the printing can only use the network to reproduce the original manuscript of the continuous adjustment level, if the enlarged view, you will find that is composed of numerous outlets of different sizes. We see the network size, although different, but occupy the same size of the space position, this is because the original image after screening, put the image is divided into numerous rules arranged in the network, that is, continuous tone image information into discrete points Image information. The larger the dot, the darker the color, the darker the level; the smaller the dot, the lighter the color, the brighter the level. The fixed space position of each dot is determined by the number of screens, for example, 150 lpi for 150 dots per inch of length or width. The location of dot space and dot size are two different concepts, for example, C50% represents the meaning of the network size of the network space accounted for 50% of the location, 100% refers to the size of all network coverage dot space position, known as the printing of the " Field ", 0% because there is no network, only the network space position, so this place is not printed on the ink. Obviously the greater the number of hanging mesh, network space occupied by the smaller, can describe the level of the more delicate. In fact, the level and color of the manuscript is reproduced through the method of hanging the net.
