Printing Roll Paper: Considerations for Choosing Cash Register Paper
Release time:2025-04-22
Ordinary cash register paper and carbonless cash register paper are both produced and processed using duplex paper, and the quality of the cash register paper ultimately depends on the quality of the duplex paper used. To achieve better performance, material selection should be the first consideration. Typically, paper with a pure white, flawless surface is made from wood pulp, resulting in cash register paper that boasts excellent tensile strength and a clean, professional appearance. In contrast, paper made from mixed pulp or straw pulp will inevitably contain some impurities—this is quite noticeable—and often exhibits weaker tensile strength, making it prone to tearing during the printing process. In fact, what truly matters is the paper's smoothness: cash register paper with superior smoothness can significantly reduce wear on the print head, delivering sharper, higher-quality prints.

Thermal cash register paper is specifically designed for use in thermal printers, and its quality directly affects print quality, longevity of the paper—and even the lifespan of the printer itself. Typically, thermal cash register paper consists of three layers: the bottom layer is a paper base, the second layer is the thermal coating, and the third layer serves as a protective layer. It’s the thermal coating or the protective layer that primarily determines the paper’s performance. For instance, if the thermal coating isn’t applied evenly, it can result in uneven ink density during printing. Additionally, if the chemical formulation of the thermal coating is improperly balanced, it may significantly reduce the paper’s shelf life after printing. The protective layer also plays a crucial role in extending the paper’s post-print durability, as it helps absorb certain types of light that could trigger unwanted chemical reactions in the thermal coating, thereby slowing down the degradation process of the cash register paper.
Methods to identify thermal cash register paper: First, examine the paper’s appearance. High-quality thermal cash register paper features a uniform color, excellent smoothness, high whiteness, and a slight greenish tint. If the paper appears overly white, it indicates that the protective and thermal coatings are improperly formulated—likely due to an excessive addition of fluorescent powder. Additionally, if the paper lacks sufficient smoothness or looks uneven overall, it suggests an uneven coating application. And if the paper reflects light intensely, this also points to an overabundance of fluorescent powder. Next, test the paper by applying heat. Carefully warm the back side of the paper with a flame. If brown discoloration appears on the surface, it signals that the thermal formulation may not be optimized, potentially leading to a shorter shelf life. On the other hand, if fine streaks or irregularly colored patches emerge in the blackened areas, this confirms uneven coating distribution. Finally, high-quality thermal paper, when heated, should turn a deep black-green hue with uniformly colored blocks that gradually fade from the center outward toward the edges.
