Need help for inreasing jpg file size

Recommended Posts

Hello guys!!!

 

I came accross a vinyl fascia that needs to be printed.  The guy has a 150 X 150  size jpg files but the fascia is 2.5 metres by 1.2 metres.  It has a lot of details (being for a local community grocery store, it has a lot of pics of spices and misc items). Is there any command or feature available in any of the following softwares to increase the jpg file size or redraw it without compromising with the quality?

 

Adobe IllustratorCS6

Flexi Starter 10

Corel Draw X6.

 

I mucked around and called some signage guys and was told that one and the only one way is to import the file in photoshop and redraw it as a whole.

 

:huh:

 

regards

Recreating the raster file as a vector file would seem like the desirable approach.  The resulting vector would be resolution independent.

 

This means tracing over the image by hand with the Pen tool in Draw, Illustrator, Inkscape or any such vector program.  Sometimes the auto-trace tool can do it.  But often it is no magic bullet except for simple cases.  This is sometimes daunting if one has never done any such tracing.  But it is an absolute must have skill in many cases.

 

Youtube has a great number of tutorial on this.

There is sometimes a little to be gained through different types of 'upsampling' but,

most often, (as dc stated) in extreme cases (like yours sounds)manual redraw

yields the most exemplary results.

Post the offending jpg, and as everyone can see you are dedicated to this, albeit new to it all, I am sure an outpouring of suggestions if not a outright solution will follow.  Plus, you don't wan't to recreate in Photoshop, it would still be raster.  Illustrator or Draw would be vector.

Sorry bevins... gotta call you on that one. Though Photoshop's notoriety is

through it's excellence in pixel based image work, it is certainly vector capable. 

I create and/or trace and redraw Vector (paths) in Photoshop all

the time then File>Export>Paths to Illustrator as a .ai vector.

 

Most people don't realize (or use) the vector capabilities of Ps.

... and one of the most intuitive Pen tools out there, IMO.

Yes, it can deal with paths.  A TIFF file will hold path information also, but I wouldn't use in a vector workflow.  But why would you use PS when you also had Illustrator?  Maybe I am just too Draw centric.

Perhaps "all the time" should have been "many times in the past".

As in "not so much lately as I have better tools than Ps for vector work"

 

However;

My main point is that Ps indeed has useful vector capabilities.

 

For simple projects where there are several pixel based modification

or separation techniques planned to prepare for trace/ redraw, it's easy

for me to grab the pen tool and do the path work for initial boundaries or shapes.

 

Just another arrow in my quiver, I guess... Since no software seems to perfectly cover all the bases,

proficiency in many (Illustrator, Inkscape, VinylMaster, Photoshop and inDesign)

feels like the bases are well covered plus greater tool-chain flexibility and options.

I will give photoshop a try but I have been told it takes forever; not the tracing but the cleanup.

Not a chance of making that a sharp, usable image for a print 2.5 meters long.

 

If you can secure hi-res images of the individual items that are on the plate,

I can create a replica, but, that one's beyond use at that size.

 

... and what is that hanging down from the top edge? Bread?

You can't make a silk purse out of that......

 

Recreating it from scratch is all you can do with a file that size.

Just a quickie...

(Why do I use Photoshop, bevins?... 'cause I can. :)

...and for many projects, It already does what other software

wishes it could do and because of that, and most importantly, it sells jobs.

This file I created in Ps at 600 dpi at 28,000 pixels wide.

It is ready to print without pixelation or the sacrafices vectors would force

on the veggies and bread. This is , for obvious reasons, a low-res version.)
