Great traditional A4 eye test poster design but with Pi, rather than letters. Statement poster for a modern home and maths fan as Pi is to 79 decimal points. Great quality to print as an A4 (210 x 297 mm, 8.3 x 11.7 in) poster and as an A5 (148 x 210 mm, 5.8 x 8.3 in) greetings card. You will receive a high resolution, 300 dpi, digital cmyk A4 PDF file and an A4 rgb JPG file of your image, both available as instant downloads. The pdfs and jpgs we send out are suitable for printing from a desktop printer and the pdf on a digital press at the size purchased. We do not recommend printing the image any larger than the original size, whilst reducing more than 50% will reduce the quality of the linework and may fill in. We recommend you print on coated stock. If you wish a different file size or type then please do get in touch, we are always willing to help. After you purchase your order you will receive an e-mail from Etsy stating that your order is ready to download. The watermark "typeonwalls" won't appear on your purchase.
