Save as vectorized PDF

Hello,

I created an image that needs to be printed on a sign panel (8700x870 cm). While I managed to create the image in Photoshop (which is 3000x2143 px), the printer is asking for a vectorized PDF file to avoid pixelation when enlarging it.

However, I do not understand/how to do this. The first PDF file I sent does not seem to be suitable. Can anyone tell me how to vectorize it? What options should/should not be checked when saving as PDF? (I don’t have Illustrator, so if you have a solution...)

Thank you in advance and have a great day!

Hello

your printer requires that the elements of the image be vectorized: objects, texts, frames, etc.
if you have pixelated the elements, they will degrade when enlarged.
the only remedy since you don’t have Illustrator to vectorize properly is to take your PSD and correct it using only the vector tools and commands
Photoshop has a vectorization option in the paths panel
the results are quite average and often require manual redrawing of the paths, but for simple shapes it might work....
as for the texts, they are vectorized upon typing and must remain so until the end of the work.

Hello,

Thank you for this response. Unfortunately, I don't understand everything; I'm not a Photoshop pro, I manage as best as I can.
Also, when I created the file, I used paths to make my images, and the rest is mainly text. I understand that when enlarged, it will look terribly bad... I'm in my PSD but I don't know how to do what you indicated.
Please note that I have all my "source" images in another PSD, available with their path (maybe that could be useful for me?).
How do I use "vector tools and commands"?

Thank you,

In enlargement, it won't look bad if done properly.
It is true that, in principle, a job like yours is done in Illustrator.
In Photoshop, it's possible but it can be complicated depending on the effects you want, or even impossible.

If you used paths to create the objects in the image, no problem.
Unless you pixelated them afterwards.
For example:
Let's suppose you created a shape and you want to apply a gradient to it.
If you use the gradient overlay in the styles or the fill/stroke panel, your shape remains vector.
If you go through the gradient tool, Photoshop forces you to pixelate.
The same goes for filters; in Photoshop, they can only be applied to dynamic or pixelated layers.

I have all my "source" images in another PSD, available with their paths (maybe that can be useful for me?).
Certainly, good initiative!
If you pixelated along the way in the montage PSD, it will allow you to recover your objects intact to correct the work and restore what needs to be vector.

How to use "the tools and commands in vector"?
Whenever Photoshop asks you to pixelate: think!
There are elements for which it won't matter: a blur for example
and others for which pixelation will ruin your work when enlarged.
In general, pixelation can be avoided by using the right tools: vector shape tools, styles, the fill/stroke panel, vector clipping techniques, vector masks, etc.
