Final print assurance2/2/2024 Sampling is another method to monitor and test print quality. If the media you have implemented causes even one print quality problem that led to a customer chargeback, the material savings would be offset several times over by the resulting fines, returns processing expenses and lost customer confidence. Even though these options will save money initially, in the long run you will be risking print quality that could create even more expensive problems down the road. Users will usually be able to find lower-cost options that have not been specifically certified or recommended. Labeling systems integrators or the printer manufacturer will recommend several acceptable options. Labels and ribbons must be matched to each other and also to the usage conditions they are required to perform in to ensure proper imaging performance. Purchasing managers must also be trained in regards to the impact media has on print quality and overall operational efficiency. When label material and ribbons are loaded correctly every time with thorough operator training and review, you will be able to prevent many wrinkling and uneven printing problems. Media selection and handling are also highly manageable variables that affect quality. The investment made in time and materials for regular printhead cleaning is repaid many times over because of the costly printhead failure problems it prevents. Inexpensive materials can make printhead cleaning quick and convenient. Cleaning the printhead every time the ribbon is replaced in thermal-transfer printing, or at every media change for direct thermal printing, should be satisfactory for most users. The applicator material is specifically designed not to stick to the printhead and leave debris.īusinesses that use label printers should make printhead cleaning part of their regular operational routine. Printer cleaning products are specially formulated to lift dirt and grease from the printhead and quickly evaporate which won’t leave a buildup behind. Before burning out, blocked elements create print quality problems by producing voids or lighter images.īuildup and related problems can be prevented through regular cleaning with specialty printhead cleaning products, including pens, swabs and cards. After continuous exposure to heat, the contaminants become hardened and baked onto the printhead, which can cause corrosion. This will require replacement of the printhead. When dirt, dust and other contaminants collect on the printhead they can block heat transfer, which can cause other printhead elements to overheat and burn out. One estimate claims abrasion is responsible for more than 80 percent of failures. Abrasion is the major leading cause of premature printhead failure. The regular cleaning of printheads protects against sudden failures and quality degradation over time. The following steps will show how to incorporate each element into a sound quality assurance plan. A well-maintained printer with scheduled cleaning and maintenance can produce several hundred thousand consistent, high-quality labels. A printer quality assurance plan should include each of these vital procedures. A consistent print quality, as well as an extended printhead life are both achieved with regular cleaning, media management, sampling and replacement of aging parts.
