Braille Labeler Parameters: How to Accurately Control the Height of the Dots
The height of the dots on a Braille label directly affects the quality of the tactile experience.In three areas-pressure, material, and temperature-the company provides detailed information on how to adjust the machine's parameters to solve problems such as unevenness and wear of Braille dots, ensuring that the printed Braille meets international standards.
Why is the height of the dots so important?
The height of the bumps is the key factor in the readability of Braille.If the points are raised too much, they are easily damaged, but if they are too low, it is difficult to feel the shape.According to international standards, the height of the dots in Braille should be between 0.5 and 0.6 millimeters, but in practice, the thickness of the material and the pressure of the machine can cause deviations.Don't worry, we'll give you some tips on how to regulate your emotions.
The key parameters of the process.
Step 1: Adjust the pressure.
The pressure is a direct factor in determining the quality of the finished product.We recommend starting with a low pressure, such as setting the pressure at level three, and then touching the sample with your hand to see if the raised area is clearly discernible.If the material is too flat, increase the pressure by 0.5 increments until the texture is clear but the material is not excessively compressed.Note that different materials (such as paper and plastic) require separate storage parameter schemes.
Step 2: Choose the right thickness.
Too thin a material (such as 70g paper) is easily perforated, and too thick a material (such as 200g card) may cause the machine to overload.We recommend using 120-160g special braille paper, and choosing the corresponding "material thickness" option in the machine settings. The system will automatically adjust the pressure parameters.
Step 3: Control the heating temperature.
For thermal transfer printers, attention must be paid to the heat setting.If the temperature is too high, the material will deform. It is suggested that the initial temperature be set at 60 ° C and the edges of the marking be observed to see if they are smooth.If the paper has burn marks or rough edges, then the temperature is reduced by 5 ℃ at a time.In winter, when the environmental temperature is low, the air temperature in the greenhouse can be raised 5-10oC.
Tips for daily maintenance.
If the height of the raised and depressed portions is unstable, it may be due to wear on the machine components.Each week the needle heads are cleaned with a cotton swab to remove any residue, and every month the tracks are lubricated.If the height difference between dots from the same batch exceeds 0.1 millimeter, the spring module must be checked and replaced if necessary.
What should we do when we encounter a problem?
Beginners often encounter situations where the middle point is higher than the edge, which is usually caused by the platform not being level.The operator places an alignment card on the work surface and then turns the four manual knobs to ensure that the laser's positioning point always falls on the center of the card's grid.If you can't figure it out yourself, contact the manufacturer to ask for a video tutorial on how to set it up. Most brands offer remote guidance services.
