வெப்ப காகிதத்திற்கும் பூசப்பட்ட காகிதத்திற்கும் என்ன வித்தியாசம்
The differences between thermal paper and coated paper mainly include storage time, temperature influence, carbon ribbon, price, etc.
Storage time:the storage time of coated paper is longer than that of thermal paper;
Temperature effect: the temperature effect of coated paper is smaller than that of thermal paper;
ரிப்பன்:Coated paper needs carbon ribbon but thermal paper does not;
விலை:Coated paper is more expensive than thermal paper.
The differences between thermal paper and coated paper mainly include storage time, temperature influence, carbon ribbon, price, etc. The specific differences are as follows
1. சேமிப்பக நேரம் வேறுபட்டது:
The storage time of coated paper is a little longer than that of thermal paper, so when you buy which kind of லேபிள், you need to decide according to the storage time of the products you stick.
2. The influence of temperature is different:
Coated paper is less affected by temperature, but heat-sensitive paper is greatly affected by temperature, so if the label attached to the product surface is greatly affected by temperature, the printing factory generally recommends choosing coated paper.
3. The ribbon is different:
This is the most intuitive difference between these two categories. Coated paper needs to be printed with a ribbon, while thermal paper does not need a ribbon for printing, and can be directly installed in a barcode printer for printing.
4. வெவ்வேறு விலைகள்:
The price of coated paper is relatively expensive, and can be customized according to the needs of customers. If there are samples, they can be printed directly according to the samples. The most important thing is that the quotation is not based on how much a sheet is, but is determined according to the printing quantity. The more, the more cost-effective the price.
Thermal paper is also known as thermal fax paper, thermal recording paper, thermal copy paper, and thermal copy paper in Taiwan. Thermal paper is a kind of processed paper. Its manufacturing principle is to coat a layer of "heat-sensitive coating" (heat-sensitive color-changing layer) on high-quality base paper. Although there are more than a dozen kinds of chemicals used in this color-changing layer, there are at least the following compounds: leuco dyes, which have a wide variety of dyes, and fluorescent compounds are the most commonly used; Phenol and p-hydroxybenzoic acid; sensitizers account for less than 10%, which contain benzenesulfonamide compounds; fillers account for less than 50%, commonly used calcium carbonate (particles); adhesives account for less than 10%, Such as polyvinyl acetate; stabilizers, such as dibenzoyl terephthalate; lubricants, etc. Therefore, the process is difficult and the technical requirements are high.
Coated paper is also called printing coated paper. A layer of white paint is applied on the surface of the base paper, and it is processed by super calendering. The surface of the paper is smooth, the whiteness is high, and the performance of ink absorption and ink retention is very good. It is mainly used for offset printing and gravure printing with fine screen lines, such as high-end picture albums, calendars, books and periodicals, etc. The disadvantage is that the powder is easy to stick and fall off after being exposed to moisture, so it cannot be stored for a long time.
