I am designing a personalized crest and a 'photo call' background (like for movie premieres) for a wedding (mine, actually).
I've done two mock-ups/versions of the wedding crest (white and navy blue backgrounds), and I will need to incorporate these wedding crests into a checkerboard pattern design for the photocall background.
Here's a mock-up of the photo call - each square is about 10x10 inches. 9 squares tall, 15 squares across. So that's 90 inches (7 1/2 feet) tall, and 150 inches (12.5 feet) wide.
My questions are thus:
The stock elements/images I'm planning on using to make the wedding crest are pretty large files in and of themselves (the floral crest, the rose, etc.). If I use those wedding crests in a repeating checkerboard pattern, wouldn't it stand to reason that the file size would get un-manageably massive? For example, each 'square' (crest, rose bud, silhouette) will be roughly 5000 px x 5000 px or 16.7″ x 16.7″. If you multiply that by 9 (# of squares tall) and by 15 (# squares across), the pixel count is immense.
I am a novice graphic designer (not in the professional sense). I'm not very comfortable with Adobe Illustrator and vector images, and would prefer to use Adobe Photoshop and JPEG images instead. The JPEGs available for download are 300 DPI and large, so I'm fairly sure the quality would be high enough to print on a photocall background. Is this OK?
These are the 4 stock design elements (from Shutterstock) that I intend to download to make the personalized wedding crest:
(A) Floral Crest (navy blue) (Large | 5000 px x 5000 px | 16.7″ x 16.7″ @ 300 dpi)
(B) Floral Crest (white) (Large | 5000 px x 5000 px | 16.7″ x 16.7″ @ 300 dpi)
(C) Red Rose Bud (Large | 5000 px x 5000 px | 16.7″ x 16.7″ @ 300 dpi)
(D) 'Marie Antoinette' profile silhouette (Small | 763 px x 800 px | 2.5″ x 2.7″ @ 300 dpi (Vector image available as well))
(NOTE: Each of these files have a JPEG or Vector download option.)
