Pls, list in details the steps i should take to make the following a success:
I have to design a truck artwork, around 321 cm by 230 cm.
I have to include a raster element picture which is gonna take almost full space.
The picture is currently 5000 by 4000 px at 72 resolution.
My workflow is as follows:
1. I create Photoshop doc at 32.1 by 23 cm at 900 dpi.
2. I opened the image another tab, and process it, i opened the image size menu and changed 72 dpi to 900. No other options touched in this dialog box.
Q1 From this point, do i save it as PSD or do i drag it directly into the Photoshop doc (No .1)
Q2 Suppose I do not do the step 2 and instead I place the picture (5000x4000 at 72 dpi) directly in the 900 dpi doc, is that ok, or what is the best way?
The main control in Image size dialog is the resample checkbox. Unchecked all that will change in the image resolution. The file size and image pixels will remain the same. What ever size setting you change the 5000x4000px will remain. All that changes is the resolution the size pixels the image will be printed with. The density the pixel will be rendered at the print size changes accordingly.
A document hat one Resolution it to place a 5000x4000 72 dpi image into a 900dpi resolution the 5000x4000 pixels will placed into the 900DIP document and hat the document resolution. IT print size will be much smaller in the 900dpi composite. Additionally if the 900DPI document canvas size is less than 5000x4000px the smart object 5000x4000 pixels will be scaled by the place transform to fit within the document canvas szde. The object size remains 5000x4000px. If the place is not scaled or you use paste to past in the 5000x4000 px the new layer will be larger the canvas size and the document canvas will act as a clipping mask. You will not see the pixels outside the documents canvas size.
Where does Illustrator come into play. It seems you have not described what you are doing and how you are processing your work. How can we help if we do not know what you want to do. I can not help for I do not use Illustrator and know little about just know it Adobe application for editing vector documents. Have no ideal about what size document it can handle or if it even supports Photoshop's raster images. Start by describing what you are trying to do. Large Prints just states you want to print large size images.
Illustrator should handle your dimensions in cm's. You can work in actual size and edit first in photoshop with decent quality (72-100 ppi is ok), then place that image in illustrator and finish your job there.
if Illustrator doesn't allow you to make an artboard full size you can do it at 1:10 scale and export at 10x dpi (72x100=720) that will compensate for the loss of resolution, just inform your printer that you've done that.
BTW Photoshop should be able to handle the full scale artwork if needed as a psb at output resolution.
Talk to the printer - you should never have to build your file at full size. They should be able to give you specs to build your files to scale and they enlarge using their RIP system to output at full size.
