S Full Screen?? Fabric Special Printing Technology

{flickr|100|campaign} As the foil itself, metallic, texture hard, soft fabric, if required on printing, graphic design should not consider a large area printing, suitable only for point, line a small area of printing.

Transfer foil to prevent incomplete or washed off the affected part of the foil of the overall pattern of appearance, and therefore the depth of color when printed on adhesive with foil to approximate as much as possible, match.

Adhesive after the drying screen printing directly affect the level of the transfer foil effect, close to the dry state is appropriate under the hot hot.

Hot pressing temperature and time to consider the tolerance level of fabric, some fabrics can be high, it can not transfer printing.

Hot pressing temperature and time determined according to the performance of adhesives. Hot hot temperature is usually not too high, high (hot stamping foil coated with the adhesive itself) not easy to transfer the graphic part of the adhesive.

Foil strip of paper must be very careful to follow the economic fabric (weft) direction of lift, pull the line to prevent the glue off, the speed can not be too quick to tear when peeling.

2. Photoluminescence printing. photoluminescence characteristics of printing. Photoluminescence printing paste printing using a special coating, the printing paste contains Photoluminescence of solid and other additives. Photoluminescence of solid irradiated by light in the dark to light, and can maintain a certain time (about 20 minutes), then later by illumination with light effects. Photoluminescence loaded with flowers do not contain radioactive substances harmful to humans.

Photoluminescence similar to printing and general printing. There currently printing paste made of luminous yellow, green, orange-red in three colors.

Photoluminescent material can be printed on various types of fabric printing on cotton fabrics, polyester fabrics printing, washing and rubbing fastness are very good.

Photoluminescence emission printing a long life. Usually within three years after printing fabric with glow.

Using photoluminescence for fabric printing in the dark crystal display colorful patterns, the fabric has a dynamic effect.

photoluminescence printing purposes. Its decorative fabric is very effective, especially children’s clothing designs printed on a variety of animals, shimmering in the dark to see, life-like images is fun.

Photoluminescence printing has its practical effects, such as: military, railway, mining, theaters and other clothing on the signs of staff, using photoluminescence printing in the dark for easy identification.

Photoluminescence printing and other specialty printing should be received with better results. Printed in bright light alone is that nearly as good special effects and even look good no ordinary stamp, these are the fabric product design should be taken into account.

photoluminescence printing equipment and materials. This general printing equipment and printing materials can be used without special requirements.

Photoluminescence printing process and precautions. A. Photoluminescence printing process. Luminous pulp products in accordance with the requirements of operating instructions, the process similar to ordinary printing. After printing required 160 ~ 185 for 2 minutes under the heat fixation treatment.

B. to attention. Fabric to ensure a better light effect, luminous plasma that can not be mixed with other substances, in order to get a better screen printing adaptability, if necessary, adding water or emulsion slurry adjusted.

Order to ensure the luminescence, light syrup should not overprint the other coating slurry, the slurry must not be covered by other coatings.

To ensure a good fabric for screen printing paste volume and better adaptability, usually not too high mesh screen to less than 100 mesh / inch as well. To ensure a clear pattern, the edge of the neat, photographic plate used in the bridge of better plastic.

Fabric product design from the specific needs of the artistic effect, day and night viewing and printing technology with the situation with other comprehensive considerations. Order should be the last luminous screen printed paste.

3. Fluorescent printing. Printing is different from the fluorescent light printing. Fluorescence was first discovered in natural fluorspar (also known as fluorspar), in the presence of ultraviolet light (such as sunlight) of irradiation, can send a non-primary color light of the flash shade. Flash is not as high as fluorescence caused by the reflection of light generated when the removal of light, it would not reflect light and flash phenomena, and this is different from the phosphorescent. Fluorescence is a flash, it can be seen reflected ultraviolet light, so that increase in the number of reflected light, the brightness increases. Such as the common fluorescent brighteners, which can absorb light in the back to the naked eye can not normally see reflecting UV and blue or blue green, offset each other’s complementary color cotton on the yellow, so that more white cotton. Fluorescent paint is not a light-emitting dyes, in short, it is a primary color with a fluorescent brightener, ultraviolet levels are the more it gives stronger fluorescence, and its main color will not increase concentration, in the absence of UV monochromatic visible light irradiation, it was not only the main color is fluorescent, which is fluorescent paint (or dye) is different from place to dye. For example, use normal dye (such as the base Sky Blue) dyed fabric, ultraviolet radiation in a large, become black instead of blue lake, as blue-green and UV light without any visible light, but if the strong fluorescence The base fabric dyed red rose in the same UV radiation, will produce a bright red and yellow fluorescence, which indicates that it can short-wave ultraviolet light within the eye become visible long-wave.

Dye absorbs light in the light quantum, the dye molecules to be intensified to become intensified state, through molecular collisions or other effects, can release a variety of different forms of energy absorbed. Forms of energy released can be heat, light (ie fluorescence), chemical energy (mainly photochemical), it can be decomposition of energy (the decomposition of dye).

General dyes is to absorb the energy into heat, only a small part of the decomposition into energy. Fluorescent dyes are converted to light energy, only a small part of the conversion to heat and chemical energy. As the fluorescent paint (or dye) and then the reflected wavelength of light, certainly longer than the absorption wavelength of the light, the issue of the fluorescence band is always in the absorption spectrum of long wavelength side of the band. The result is yellow and blue dye absorption, fluorescence is blue-green (or green). Therefore, the yellow fluorescent paint than by the general non-fluorescent yellow dye or hair bluish green. While fluorescent paint (or dye) will increase the number of reflected light, often several times larger than the original. The more the number of reflected light, the fluorescence better, fluorescent degree
