How to Test Metal Type
Metal type, also known as metal type casting, is an ancient printing technique that involves the use of molten metal to create individual letters and characters. This method was widely used before the invention of modern printing technologies. Although it is not as common today, understanding how to test metal type is still valuable for historical research and for those interested in the art of printing. In this article, we will discuss various methods to test metal type and ensure its quality.
Firstly, it is essential to examine the metal type for any signs of corrosion or damage. To do this, hold the metal type under a bright light and look for any rust or discoloration. Corrosion can weaken the metal and affect the readability of the character. If corrosion is present, it is advisable to clean the metal type with a soft cloth and a mild cleaning solution.
Secondly, check the metal type for any inconsistencies in the shape or size of the letters. Uneven or misshapen letters can cause problems during the printing process. To test the consistency, compare the dimensions of several letters of the same typeface. If there are significant differences, it may indicate a problem with the casting process.
Another crucial aspect of testing metal type is verifying the accuracy of the letter shapes. This can be done by comparing the metal type to a known standard or by using a template. Place the metal type on the template and check for any misalignments or deviations from the expected shape. This step is particularly important for custom or rare typefaces.
Additionally, inspect the metal type for any imperfections or burrs on the edges. These can cause issues during the printing process, such as uneven ink distribution or jamming. Use a fine-grit sandpaper or a file to gently smooth out any burrs or sharp edges.
One effective way to test the overall quality of metal type is to print a sample page. Create a layout with various metal type characters and print it on a sheet of paper. After printing, examine the page for any issues, such as blurred letters, uneven spacing, or misaligned characters. This will give you a good indication of the metal type’s performance and potential problems.
Lastly, consider the age and origin of the metal type when testing its quality. Older metal type may have been subjected to harsh conditions and may require more thorough examination. Additionally, metal type from different regions may have variations in quality and design, which can affect the testing process.
In conclusion, testing metal type is an essential step in ensuring its quality and usability. By examining for corrosion, checking the consistency and accuracy of the letter shapes, smoothing out any imperfections, printing a sample page, and considering the age and origin of the metal type, you can determine the overall condition and suitability of the metal type for your printing needs.
