Disadvantages are that they are pricey, demand highly-priced curing modules during the printer, and also the cured ink has a major volume and so provides a slight reduction about the surface. Although enhancements are being manufactured while in the technology, UV-curable inks, as a consequence of their quantity, are somewhat susceptible to cracking if applied to a flexible substrate. As a result, they in many cases are used in large "flatbed" printers, which print directly to rigid substrates including plastic, wood or aluminium where adaptability is not really a priority.
