Olá, sou novo aqui no fórum e não sou designer, mas me pediram no trabalho para melhorar uma imagem para impressão em tamanho grande, o tamanho que me pediram é 1,80 de largura e 1,5 de altura.
Gostaria apenas de saber se uma imagem de 3200 x 1600 px ficaria boa nessas proporções,
Eu também tenho uma imagem de 4096 x 2048 px.

Agradeço antecipadamente
 
Sorry, I had to run your post through Google Translate as I don't know Portugese. Here's what it gave me:
Hello, I'm new here on the forum and I'm not a designer, but I was asked at work to improve an image for printing in large size, the size I was asked for is 1.80 wide and 1.5 high.
I would just like to know if a 3200 x 1600 px image would look good in these proportions,
I also have a 4096 x 2048 px image.

Most smaller print work would be 300dpi (or ppi) and at very large sizes you could get away with 100dpi minimum.
At 100dpi, your image would need to be at least 7087x 5906px.

If you're designing the image for print, I'd recommend a larger canvas size. If you have an image that needs to be upscaled, I'd recommend using a tool like "Upcsayl" but beware it uses AI and may not deliver perfect results (although it is quite good).
 
Firstly, thank you very much, secondly, I apologize, I swore it had been sent in English, this is not the first time I have had this problem where my browser automatically translates the message.
 
Hi, welcome to the forum!

For high-quality prints, especially for large formats, aiming for a resolution of at least 150 PPI is often recommended, though 300 PPI is better for closer viewing distances.

Dimensions in inches:
1.80 meters wide = 70.87 inches
1.5 meters high = 59.06 inches

For the 3200 x 1600 px image:
Width: 3200 px / 70.87 inches = 45.14 PPI
Height: 1600 px / 59.06 inches = 27.09 PPI
At approximately 45 PPI (width) / 27 PPI (height) will likely appear pixelated when printed at the requested size.


For the 4096 x 2048 px image:
Width: 4096 px / 70.87 inches = 57.78 PPI
Height: 2048 px / 59.06 inches = 34.67 PPI
At approximately 57.78 PPI (width) and 34.67 PPI (height), this image will be slightly better but still far below the ideal print quality.
This will also look pixelated, although slightly less so than the 3200 x 1600 px image.

You'd need an image with a higher resolution, ideally 5280 x 4410 pixels (150 PPI).

If higher resolution images are not available and the image will be viewed from a considerable distance, the 4096 x 2048 px image might suffice, but it won't be crisp and detailed.

What can you do
Adobe Photoshop or specialised upscaling software (e.g., Gigapixel AI) can help improve the resolution, but results can vary.

If possible, use vector graphics which are resolution-independent and can be scaled without loss of quality.



Another consideration: viewing distance
Here’s a basic guideline

Up to 1 foot (0.3 meters): 300 PPI

1 to 3 feet (0.3 to 0.9 meters): 150-200 PPI

3 to 10 feet (0.9 to 3 meters): 75-100 PPI

10 to 20 feet (3 to 6 meters): 30-75 PPI

Over 20 feet (6 meters): 20-30 PPI


Let’s assume your large print will be viewed from a distance of about 10 feet (3 meters) or more. Based on the above guidelines, you can use a resolution as low as 30 PPI for acceptable quality.

The image might still appear somewhat pixelated when viewed up close but could be acceptable from a distance of around 20 feet or more.


  • For the 3200 x 1600 px image, the ideal viewing distance is around 7.9 feet.
  • For the 4096 x 2048 px image, the ideal viewing distance is around 6.2 feet.
