I'd like to make a 1X4M light box advertisement. The box is there and the ad paper wants to be packed. I don't know. How much would it cost to make such a light box paper or a light box cloth? Including paper and inkjet fees, CF
Considering your transmittance, the inside of the background panel you can use plexiglass. Transparency and smoothness are excellent. That's the high price. 3 square price at around 120 yuan.
You hang on for a long time. I suggest you use a good inkjet. Choose 0.7 thickness, the cost varies from place to place, probably around 8 in price. If you are short-term hanging, then use a high grade photo paper, that effect is much better than inkjet printing.
Outdoor printing cloth you said, the price is very low, here is 6 yuan / m2, the highest is 12 yuan / square, in addition the installation fee plus the size of you there, because this is not expensive, or persuade you to let a professional to help you install it!
