What should I do if I need more help after reading the Artwork Submission page?

Use the contact or support options linked from the Skyline store and include the relevant order or product details. Submit editable Adobe artwork at 10% or 100% scale, use raster images at 100 ppi at full print size, outline or provide fonts, link included assets, and follow the product template for bleed. Native Illustrator, Photoshop, and InDesign files are preferred; editable PDF, JPG, TIF, PNG, and EPS are also accepted. Source: https://shop.skyline.com/pages/artwork-submission
