Recommended resolution
We often get questions about resolution.
The recommended resolution for PHOTOPRI is 350 ppi.
The resolutions in the table below are acceptable values, taking into account that A2 size and larger images will need to be viewed from a certain distance.
Even with a lower resolution, you can often get a very clear output result as long as the pixel count is met.
| Print Size | Acceptable resolution | |
|---|---|---|
| A4 | 210×297mm | 250ppi or more |
| B4 A3 |
257×364mm 297×420mm |
240ppi or higher |
| B3 A2 |
364×515mm 420×594mm |
240ppi or higher |
| B2 A1 |
515×728mm 594×841mm |
200ppi or higher |
| B1 A0 |
728×1030mm 841×1189mm |
180ppi or higher |
| B0 | 1030×1456mm | 180ppi or higher |
- Resolution will vary depending on the customer's desired values, so please make your own judgment.
Note
Even if you enlarge original data that does not meet the recommended pixel count or resolution using image editing software, the image quality may become rough, but it will never become clearer.
Test print
Just like taking a test drive before buying a car, we would like you to try out our trial printing service and experience the paper with your own eyes before printing.
There are a wide variety of papers available, including glossy paper, matte paper, fine art paper, and Japanese paper, and you can't really understand the texture, feel, and color transfer that each one has until you actually hold the printed material in your hands.
It can be difficult to choose the best paper from the many available options right away. There are many people who don't know which one to choose.
You can use your own photo data to print the test print.
If you have never ordered a large format print, we accept orders for just one piece, so please take advantage of this opportunity!
