Question

Seal

Hello, the question is this: now I'm making a banner for an event, in PS its dimensions are 600x1000 pixels.
Next, you need to send it to print. The banner will be about 1.50 in height and proportional in width
, so the question is .. Will the quality be lost when printing?
The resolution is 150 pix.inch
And what should be the dimensions for the picture so that it does not float

Answer 1

600 by 1000 pixels for a meter banner is very small. Draw in vector and nothing will float
