How We Keep Sign Projects Moving
Production & Delivery Process
1. Plan
Send the sign location, size, artwork, deadline, and any landlord or brand requirements so we can point the project in the right direction.
2. Approve
Review a clear proof before production starts, including scale, color notes, material, mounting details, and any file-prep fixes.
3. Produce
Your sign is printed, cut, painted, finished, and prepared for pickup, delivery, shipping, or installation, depending on the project.
Installation Process
1. Survey
We look at the wall, window, fascia, access, measurements, visibility, and any constraints that could affect the install.
2. Prepare
The sign, hardware, templates, adhesives, fasteners, and install plan are matched to the surface instead of guessed on site.
3. Install
We install with attention to alignment, spacing, surface prep, cleanup, and the way the sign reads from the sidewalk, parking lot, or lobby.

Frequently Asked Questions
How long does it take to get a sign?
Simple print and cut projects can often move quickly once the proof is approved. Installed signs usually need more planning, especially if the site needs measurements, landlord review, specialty hardware, or access coordination. For San Jose and South Bay installation projects, we will give you a realistic timeline before production starts.
What areas do you service for installation?
We quote installation services in San Jose, Santa Clara, Sunnyvale, Mountain View, Milpitas, Palo Alto, Cupertino, Campbell, and Los Gatos. Site access, approvals, travel, and scope are confirmed before scheduling.
Do you handle permitting for signs?
Some signs need landlord approval, site criteria review, or city permitting, and some do not. For installation projects, we can help identify the likely approval path, prepare practical sign details, and coordinate next steps based on the property and scope.
What file formats do you accept for custom designs?
We accept common file formats including AI, EPS, PDF, PSD, and high-resolution JPG or PNG files. Vector files are best for cut vinyl, dimensional letters, logos, and clean large-format output, but we can review what you have and flag any file-prep issues early.
Do you offer design services?
Yes. We can clean up a logo, lay out a storefront sign, prep artwork for production, or help turn a loose idea into a buildable sign package. If you already have brand files, we can work from those instead of starting over.
What payment methods do you accept?
Any accepted payment method, deposit, payment schedule, and balance due date are stated in the written quote or invoice for the approved project. The website does not create a fixed deposit percentage or payment schedule.
