This guide is written for sports teams, leagues, academies, and independent streetwear brands that require professionally manufactured baseball jerseys and coordinated team uniforms. It explains how to configure, submit, and approve orders for Custom Baseball Uniforms using a structured production process.
There are two primary ordering pathways. The first is template-based personalization, where you select an existing design layout and modify names, numbers, and logos. The second is full custom manufacturing, where an entirely new graphic concept and garment layout are developed based on your specifications.
This document outlines technical requirements, file preparation standards, sizing considerations, and production procedures. It is intended to help you submit accurate information, reduce revision cycles, and ensure that manufacturing proceeds without delays. B1 Apparels operates on a structured approval-based system; production begins only after final design confirmation.
2. Understanding the Two Customization Pathways
2.1 Template-Based Personalization
Template-based personalization uses pre-developed sublimation layouts engineered for efficient manufacturing. These designs already follow established panel structures, print mapping, and grading specifications.
Editable elements typically include:
-
Team name
-
Player name
-
Jersey number
-
Sponsor logo placement
-
Minor color adjustments (within design limits)
In this pathway, the garment structure remains unchanged. Fabric composition, seam placement, and panel construction are fixed according to production templates. Because structural development is not required, turnaround time is reduced and artwork approval is streamlined.
This option is suitable for clubs requiring coordinated team uniforms with standardized formatting and predictable delivery timelines.
2.2 Full Custom Manufacturing
Full custom manufacturing involves original graphic development and may include:
-
New visual layout
-
Custom color blocking
-
Unique typography
-
Brand-driven identity elements
-
Panel restructuring when required
This process begins with artwork submission and technical review. Design feasibility is evaluated against print area dimensions and construction constraints. A digital mockup is created for approval before production is scheduled.
Because this pathway may involve new pattern adjustments and layout mapping, the approval phase is more detailed and may extend timelines. It is suitable for streetwear brands or clubs seeking distinct visual identity rather than template adaptation.
3. Technical Product Specifications
3.1 Fabric Construction
Baseball jerseys are manufactured using Polyester Performance Fabric engineered for athletic activity. Typical fabric weights range between 140–180 GSM depending on style.
Key characteristics include:
-
Moisture-wicking capability to manage perspiration
-
Breathable knit structure for airflow
-
Dimensional stability under heat transfer conditions
-
Resistance to repeated washing
Fabric selection directly influences print clarity, durability, and comfort. All materials are selected to withstand high-temperature sublimation processes without distortion.
3.2 Printing Method
All graphics are applied using Dye Sublimation Printing. This process transfers ink into the fabric fibers through controlled heat and pressure.
Technical features include:
-
Ink converted from solid to gas phase
-
Pigment embedded within fibers rather than sitting on surface
-
No cracking, peeling, or surface texture
-
Full-coverage print capability across panels
Because color becomes part of the textile structure, the garment retains flexibility and breathability after printing.
3.3 Garment Construction
Patterns follow an Athletic Fit Pattern designed for range of motion. Construction includes:
-
Reinforced shoulder seams
-
Double-needle stitching at stress points
-
Clean placket finishing (button or pullover options)
-
Balanced hem alignment
Garment assembly is executed to maintain structural integrity during athletic use. Stitch density and seam tension are calibrated for durability under repeated movement.
4. Step-by-Step: How to Order Online
Step 1 – Select Base Design
Navigate to the baseball collection and review available layouts. Confirm that the design supports your branding requirements and intended color scheme.
Step 2 – Input Team Data
Accurately submit:
-
Official team name (exact spelling)
-
Player roster list
-
Corresponding jersey numbers
-
Any captain or position identifiers
Verify spelling before submission. Errors entered at this stage are replicated in production.
Step 3 – Upload Logo Files
Submit logos in editable Vector Artwork format whenever possible. Preferred formats include:
-
AI
-
EPS
-
Print-ready PDF
If submitting raster files, ensure a minimum of 300 DPI at actual print size. Avoid screenshots or compressed web images, as these reduce edge clarity during enlargement.
Step 4 – Select Sizes and Quantities
Use the provided measurement chart. Do not rely solely on standard letter sizing (S, M, L). Compare chest width and garment length with physical measurements.
Production uses standardized Size Grading to scale patterns proportionally across youth and adult ranges. Mixed size orders are acceptable when properly specified.
Step 5 – Final Review and Checkout
Before confirming payment:
-
Recheck roster entries
-
Confirm numbering accuracy
-
Verify logo placement
-
Ensure size distribution matches your list
Production scheduling begins after final order validation.
5. How to Submit a Fully Custom Design
For full custom requests, contact the support channel specified on the website and provide the following:
-
Design references or sketches
-
Logo files in editable format
-
Quantity breakdown by size
-
Preferred color codes
If specific brand colors are required, provide Pantone Color Matching references. This helps align digital mockups with expected output, although minor tonal variation may occur during heat transfer.
After submission:
-
A digital mockup is prepared.
-
You review and approve layout and placement.
-
Written confirmation is recorded.
-
Production is scheduled.
Manufacturing does not begin without explicit design approval.
6. Artwork & File Preparation Guidelines
For accurate output:
-
Submit AI or EPS files when possible.
-
Outline all fonts before export.
-
Maintain minimum 300 DPI for raster elements.
-
Design in CMYK color mode when preparing print files.
RGB files may shift slightly when converted for sublimation processing. Avoid embedding low-resolution graphics inside vector files. Do not submit logos extracted from social media pages.
Proper file preparation reduces revision cycles and preserves edge clarity during enlargement.
7. Production Timeline & Manufacturing Workflow
The Production Workflow follows structured stages:
-
Artwork review (24–48 hours)
-
Mockup generation
-
Client approval confirmation
-
Print mapping and panel preparation
-
Sublimation transfer
-
Garment stitching and assembly
-
Final inspection
Standard manufacturing time varies depending on order volume and complexity. Template-based orders generally move faster than new layout developments.
Production scheduling is capacity-based and begins only after design approval and payment confirmation.
8. Quality Assurance Standards
Each order undergoes internal Quality Control Inspection before packaging.
Checks include:
-
Stitch reinforcement verification
-
Print saturation and alignment review
-
Measurement consistency against size chart
-
Panel symmetry confirmation
-
Final packaging review
Only garments meeting internal standards proceed to dispatch. Inconsistent items are corrected prior to shipment.
9. Common Ordering Errors to Avoid
To prevent delays:
-
Do not submit incomplete roster lists.
-
Avoid duplicate player numbers unless league rules allow it.
-
Do not upload low-resolution logos.
-
Always reference the measurement chart before selecting sizes.
-
Provide accurate color references instead of descriptive terms such as “bright red.”
Clear documentation at submission stage minimizes production interruptions.
10. Reorder Process
Reorders are simplified if no structural design changes are required. Reference your previous order number to retrieve archived layout files.
If artwork and sizing specifications remain unchanged, manufacturing can proceed without new mockup development. This reduces preparation time and accelerates dispatch scheduling.
For modifications such as added players or number adjustments, submit updated roster details clearly marked against the original version
