How is a print checked to determine if it os scalable?

To determine if a print is scalable, one typically checks its resolution and file format. A high-resolution image, ideally at least 300 DPI (dots per inch), ensures that the print maintains quality when resized. Additionally, vector files, such as those in SVG or AI formats, can be scaled without loss of quality, whereas raster images, like JPEGs or PNGs, may pixelate when enlarged. Testing the print at various sizes can also help assess whether it remains clear and visually appealing at different scales.
