If thermal paper fades, how can it be recovered quickly?
Latest company news about If thermal paper fades, how can it be recovered quickly?

It is normal for thermal paper to fade over time. Taking into account "heat" fading, paper as a chemical coating of paper, other chemical agents, water and even different kinds of oils. Considering that many people store thermal paper receipts for financial management purposes, the loss of vital information content (especially in the case of original documents) can have serious consequences, mainly including monetary and/or legal risk property damage . Fortunately, if the faded thermal paper is all white and not brown or black, it is not difficult to restore normal faded thermal paper.

How can I restore normal faded thermal paper?


1. Scan the faded thermal printing paper into a color picture, and then apply the unique attribute-specific tools of the photo editing software to create a negative image, that is, a black image, which is faded and printed as white or full white. In the open image, select the heading "Negative" or the other dedicated tool option "Create Negative", then apply other enhancements to make the original white print information clearer. For example, adjusting a certain level of contrast or smoothing or sharpening the print on an image.

2. Apply a hair dryer to create a "negative" image. If the thermal printing paper copy after adjusting the scanner will not restore the normal printing information. Turn on the hair dryer and blow the heat gently, you want to restore the reverse side of the normal faded thermal paper. Always keep the hair dryer more than 8 to 12 inches from the surface to avoid rapid blackening, which will most likely blacken the original thermal print information. If you don't have a hair dryer, use a light bulb, but keep the light bulb about 2 to 5 inches at all times, depending on the heat generated by the light bulb.

3. Store a copy of the restored thermal paper document for your records, and store the original hard copy in a cool, dry area away from UV light, water or chemically harmful substances.

Common considerations for reducing thermal paper fading:

1. The reverse side of thermal printing paper is not easily heat-shocked to form a "negative" image throughout. If the paper is loaded too close to the heat source, you are likely to lose the original thermal print information quickly.

2. Use the reverse side of the paper to heat it all the way, so you can better measure whether the thermal printing paper is reactive heat.

3. Before handling other thermal printing paper, please be sure to wash your hands and do not touch the printed information, this is because the oil on the skin and other residual oils, stains or chemical agents on the skin will cause heat. sensitive printing paper reaction area.

4. Scanner thermal paper documents to avoid backup data loss originals or accidents, which will cause thermal paper to heat up and turn brown or black and lose all printed information.
