Printing in A1 format

Frequently asked questions about the A1 format

What resolution for A1 images?

Depending on the media you wish to produce in A1 format, you will have to choose a more or less important resolution.

For large visuals intended to be seen from a distance, especially large formats such as A1, it is not always necessary to choose a high resolution.

However, for the printing of decorative photographs, it is better to choose a higher resolution in order to guarantee the quality of the illustrations.

Translated into pixels, the A1 format varies according to the resolution in dpi ("dots per inch" in English) that you will choose:

• for a resolution of 300 dpi, you will need a photo of 7 016 x 9 933 pixels,
• for a resolution of 200 dpi, you will need a photo of 4 684 x 6 622 pixels,
• for a resolution of 72 dpi, you will need a photo of 1686 x 2384 pixels.

Which paper and finishes for your A1 prints?

Several types of paper can be used for your A1 prints:

• White paper is a classic paper, frequently used for all types of printing.
• The coated paper is a paper on which one or more layers of products were deposited in order to obtain a smoother surface. The use of this paper favors a better restitution of the printed colors.
• The laid paper has an aged appearance due to the fine horizontal lines visible in transparency.
• Textured paper is slightly grainy which gives it a prestigious, elegant look. This paper is often used for printing invitation cards or greeting cards.

Regarding the weight of the paper, at Copymage, you have the choice between:

• 80 g/m2 paper - this is the paper usually used in personal printers,
• 100 g/m2 or 135 g/m2 paper - these papers offer a firmer hold and are often used for higher-end communication tools.
• 170 g/m2 paper - this paper is called semi-rigid. It makes the printed material more rigid and allows the poster to be hung in A1 format without having to frame it.
• 300 g/m2 paper - this is a rigid paper that opens up many possibilities in terms of lamination, and is particularly suitable for high-end media.

The A1 format is a large format that will enhance your communication elements. For this reason, at Copymage we advise you to take care of the finishing by choosing a lamination adapted to your support:

• The glossy lamination is ideal to magnify the photos, it offers a great intensity to the colors.
• Matte lamination offers a modern, more formal look that is suitable for prestigious communication materials.
• The soft touch lamination adds a peach skin effect to the matte finish of your A1 print, making it silky to the touch.
• The selective varnish allows you to highlight certain elements of your A1 print by making them more brilliant.
• Laminating is also available for your A1 format printed material - it extends the life of your material through its protective effect.
