I requested a lenticular business card sample. It was delivered promptly and was exactly what I asked. However the back image was unclear this then effected the font. This was an human error on my part as the image used wasn’t the best quality. On my second sample request. Twent3 informed me by phone and email that the font and image wouldn’t print well as the resolution was to low and that they wanted the best quality for my business card, regardless of it being a sample. They were very helpful, giving me advice on editing the image and even offering to edit it themselves. After adjusting the dpi. I was very pleased with the results and will be ordering again (Bulk order) in the near future. I would recommend twent3 to anyone. I would also advise making image resolutions higher (300dpi) for better results.
