Currently on the market photo paper brand variety, but the overall is divided into several different grades of products, we can use for their different levels of the printer to buy different grades of paper. As for the quality of the paper itself, we can from a number of angles to check.
First, the photo paper from the bag out of a tile on the table, wait half an hour later, look at both sides of the paper upturned or upturned. If there is upturned to prove that the paper is not qualified; if it is to the back of the next Alice will look under the angle of the next, the general phase of the normal angle of the paper in the four or five mm range, too much may be a problem, we can reverse the direction of a little Bend it. Because the upturned is the coating in the production did not control the production workshop temperature and humidity. Once the tilt is like a serious, sometimes there will be a printer does not feed paper or roll angle to the printer's nozzle leading to inkjet error.
Second, with the visual surface whether there is scratches, thorns, or black spots. If the surface of the above situation, then prove that the paper failed. Because the quality of the manufacturers used in the coating workshop are dust-free workshop, under normal circumstances, the coating surface will not appear scratches and black spots and the like, only small factories will exist in the above situation to the United States for the paper For example, their production workshop is isolated from the external environment of the dust-free workshop, production strictly control the production line technology.
Third, look at the surface smooth and flatness. Good photo paper feels smooth and smooth. And a plastic texture, and poor photo paper was dry state.
Fourth, to identify whether it is colloidal or powder coating. In the photo paper coating is divided into colloidal and powder coating. Colloidal coating cost is high, smoothness, tightness, color reduction force, and waterproof performance are far better than powder coating. Identification method: in the corner of the photo paper to the inside of the fold, and forced to fold several times along the crease. Then stretch the crease. Good photo paper in the crevice will not appear off powder phenomenon. And poor photo paper is out of powder phenomenon, indicating the use of low-cost powder coating. This type of coating has serious damage to the printer.
Five, look at the paper-based paper. At present, the domestic high-quality paper-based paper are imported base paper, such paper tightness is good, breathable waterproof, and very strong flexibility. While the poor quality of the paper just used low-cost white card as the phase paper base. This kind of paper feels thick, very poor flexibility.
Six, to identify the waterproof performance, good waterproof paper can drop a little water to the paper surface (but remember not to be too long, usually a few seconds to erase the current production technology can not prevent this drip intrusion) to observe the paper surface Whether there is water drops. Or can also be the whole piece of paper into the water for a long time soak for an hour, there is no description of the phenomenon of water are high-end photo paper. To the current domestic most of the photo paper, the general can be soaked for half an hour no problem, and then there will be a long coating of molten water phenomenon, only a few of the best brands to do and imported photo paper Can soak for several hours or even 24 hours, such as Yesion photo paper, after the test of its photo paper can be the whole breath in the bubble for 24 hours, and imports of paper than do not worry too much.
