Hi everyone, I need some advice on enlarging illustration and yet maintaining high picture resolution. I don't work in vectors and I ink my drawings and paint them in Photoshop or the traditional way. My working size is usually within a4 to a3 size. If I wanted to enlarge my work to a1 and bigger (sticker for wall mural/standee size?) how should I go about it? Please advise! :)

one way is to print it out as good quality inkjet print. Then rescan it for a bigger resolution. that way there will be low-resolution pixels.

check with your printer, they might not need exactly 300dpi to print a mural or standee. they might only need 200dpi.

it depends on what the illustration is used for.

If it's like a banner or huge poster that is to be expected to be seen like 3-6m + away, then prob only 100-150dpi is needed. But if everything needs to be sharp even when standing 1m away from it, then prob 200-250dpi is the minimum for largescale inkjet. ya should check with printer anyway to be sure.

(take note: for 100dpi, it will look pixelated if illustration is viewed 1-2m away)

For me, if i know that i need to hand draw something and colour it digitally, and i need to blow it up real big like 2-3m height i make sure i scan the hand drawn linework really high between 600-1200dpi (maybe less if you dont need it to be seen near) before colouring.

If your final work is completely hand drawn and hand coloured and you need to blow it up, there are some industrial printers who do professional super high resolution scanning for you at a small fee.

oh let me add that the resolution examples i give must take into account the file size being exact size on the soft copy specs.

eg. for a large illustration (maybe 2x2m size) to be viewed 3-6m away, the photoshop specs must be at least - image size 2x2m, resolution size 100-150dpi)
