How to recreate this image in Illustrator? need help

jdanek  wrote You said in your original post you wanted a very large print.  100cm is not very large ( 39.37" ).  You have now an image of 166.66" x 166.66" @ 72ppi ( sent to you buy the artist, congratulations on that by the way ).  So, I am not clear about your final size for the file.  You could build your Illustrator file at 100% ( 39.37 x 39.37" or 100cm x 100cm ).  Now the size depends on the final output.  It appears that your file could be printed using an offset printer and, if that is the case, then the image could be resized ( always rename the original so you always have the original file ) to 100cm x 100cm @ 300ppi using Photoshop and "Placed" in Illustrator.  The image size is doubled every 50% reduction ( 12000 @ 72ppi ÷ 2 = 144ppi; ÷ 2 = 288ppi ).  In inches you'd start with 166.666 ÷ 4 = 41.6665 @ 288ppi = 39.37" @ 300ppi ( your 100cm size ).  However, you refer to your project as "very large", so not sure what you mean.  If the printer uses an inkjet large format printer, they only need 144ppi which you can easily achieve resizing in Photoshop.  If the printer uses offset, you can still achieve the final 300ppi using Photoshop.  Your additional artwork of the "Monster Energy" logo is all good in Illustrator as vector artwork.

I thought that 100cm x 100cm is "very large" thats why I used those words hahaha. So 12000 x 12000 is 166" x 166" @ 72ppi? I still want to print my canvas painting at about 100cm x 100cm, however after reading several sources about printing, I concluded that my file should be at 300ppi if I want a high quality output. What do you mean build my Illustrator file at 100%, do you mean to create a file that is the size of 100cm x 100cm and just import my 12000 x 12000 picture that was sent to me? When I went to photoshop and opened the picture, I went on change image size and then I could change the ppi to 300 however when I did that I noticed that when I zoomed in the picture was blurrier than it was when it was 72 ppi, is this normal? does this mean that when I change it to 300ppi the outcume quality of the picture will be more pixelated and lower quality?

"In inches you'd start with 166.6/4=41.6665 @ 288ppi = 39.37" @ 300ppi (your 100cm size)" this part wasnt clear to me neither, nor " the image size is doubled every 50% reduction (12000 @ 72ppi/2=144ppi, /2=288ppi)". What are you refering this to? when I create a new file in illustrator that is the size of 100cm x 100cm or? what am I dividing? what and how do I use this information?

I have very little knowledge about all these terms and Illustrator and Photoshop in general. The only thing that I know is that I have an image (.tif and .jpg) that has a resolution of 12000 x 12000 and that I want to print this image at a size of 100cm x 100cm on a canvas. AFAIK from my little research, I need to have a file of a 300ppi so that the outcome image on my canvas will be high quality and not pixelated. Now do I need to redraw the image in illustrator @ 300ppi or what? I want the picture to be as sharp as it is in 72ppi, I mean when I zoom in @ 72ppi everything is crisp and sharp, however when I do that @ 300ppi everything is uch blurrier so would this mean that it would be like this when I print it out or? I honwstly just need a very simple termed and detailed set of instruction on what it is that I need to do to print this image at 100cm x 100cm from my .tif or .jpg 12000 x 12000 file which is @ 72ppi.

Edit: from this source Creating a High Resolution Image for Printing and Displaying Online | PicMonkey it says that to get a high quality image, I need to multiply 300 by how many inches I want my image to be, so that would be 12000, but what I have is 12000 @ 72ppi not @ 300ppi... idk if I understood everything correctly.
