Why can't we use Photoshop for vector designing & printing instead of Illustrator?

Adobe Illustrator is an advanced vector-based software. So, unlike Photoshop's pixel-based format, it uses mathematical constructs to create vector Graphics. In Illustrator, a line is composed of two dots connected by a computer algorithm, instead of just a line of pixels. Because of this, Illustrator is used often to create logos or anything that may need to be printed or displayed at different sizes. A vector graphic will never lose its quality if it's scaled up or down. Illustrator will also give you a better print output since it's not resolution dependent. A drawback of Illustrator is that it can't be used easily to modify images that are already created, since there are limited filters and image editing tools available to you.

Adobe Photoshop is a great program for modifying already created images or graphics, like photos, raster or bitmap graphic.

These graphics can sometimes look a little jagged since raster images are made up of individual colored squares, known as pixels. Everything in Photoshop is just a series of pixels, so if you're scaling something up or down, it can lose its quality very quickly. Photoshop is a popular choice for web graphics, photo editing and designs since those projects will stay at a fixed size. Editing photos is awesome in Photoshop, because it includes a lot of unique filters, special effects and tools. Another great benefit of Photoshop is that you can have complete control of your projects, since you can edit your graphic pixel-by-pixel.

Photoshop depends on its work on pixels, images and dots

It it pixel based software comparing to vector based Illustrator.

Because Photoshop use pixel with is the unit of digital imagery, we have tools in photoshop allows us to make vector work, but the illustrator is more powerful and more easy to use to draw vector shapes

Because Photoshop's pixel-based format and used for bitmaps and image editing but Adobe Illustrator is an advanced vector-based software

Photoshop is a program used mainly for image editing

Photoshop is bitmap/pixel based while Illustrator is vector. All vector based designs should be done in Illustrator – the right tool for the right job!!

Thank you for the invitation

sorry it's not It is not a field of competence

Illustrator is a program that creates shapes through calculations (vectors) so that the shape is made up of several points and this allows us to deal easily with the shapes in terms of quality and thus I can use different sizes without damage to the shape.

Unlike photoshop, it is a program to manipulate images dramatically. So you can modify a particular image at a certain size while it can not be resized to a certain extent. This is because the program is based on the principle of Pexels which are points that limit the quality of the image and vary in number depending on the quality of the image.

Because Photoshop is a raster based software and is mostly used for editing the Images on the other hand Illustrator and coral draw are vector software where you can create vector elements and combine edited raster images from Photoshop to design and print or digital artworks.
