Re:           Registration Statement on Form S-4

Ladies and Gentlemen:

I am general counsel of Cenveo, Inc., a Colorado corporation (“Parent”), Cenveo Corporation, a Delaware corporation (the “Company”) and the guarantors listed on Schedule I hereto (the “Subsidiary Guarantors” and,  together with Parent and the Company, the “Issuers”).  In connection with (i) the proposed issuance by the Company in the exchange offer (the “Exchange Offer”) of up to $400,000,000 aggregate principal amount of its 8⅞% Senior Second Lien Notes due 2018 (the “Exchange Notes”), which are to be registered under the Securities Act of 1933, as amended (the “Securities Act”), in exchange for a like aggregate principal amount of the Company’s outstanding 8⅞% Senior Second Lien Notes due 2018 (the “Original Notes”) issued pursuant to Rule 144A and Regulation S of the Securities Act and (ii) the full and unconditional guarantee of the Exchange Notes by Parent and the Subsidiary Guarantors (collectively, the “Guarantors”), I have examined the Registration Statement on Form S-4 as filed with the Securities and Exchange Commission (the “Commission”) on March 5, 2010, as amended by Amendment No.1 thereto, filed with the Commission on the date hereof (the “Registration Statement”) pursuant to the Securities Act.

The Exchange Offer is being made pursuant to the Registration Rights Agreement, dated as of February 5, 2010 (the “Registration Rights Agreement”), among the Issuers and the initial purchasers named therein. The Registration Rights Agreement was executed in connection with the private placement of the Original Notes.

The Original Notes were issued and the Exchange Notes will be issued pursuant to the Indenture, dated as of February 5, 2010 (the “Indenture”), among the Issuers and Wells Fargo Bank, National Association (the “Trustee” or “Collateral Agent”). The Exchange Notes and the Indenture are each governed by the internal laws of the State of New York.

I have examined and relied upon the originals, or photostatic or certified copies, of such records of the Issuers and certificates of officers of the Issuers and of public officials and such other documents as I have deemed relevant and necessary as the basis for the opinions set forth below.

In my examination, I have assumed the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to me as originals and the conformity to original documents of all documents submitted to me as copies. In addition, I have assumed the Registration Statement, and any amendments thereto (including any post-effective amendments), shall have been declared effective under the Securities Act and its effectiveness shall not have been terminated or rescinded, and that the Indenture shall have been qualified under the Trust Indenture Act of 1939, as amended. As to any facts material to these opinions, I have relied to the extent I deemed

2 

appropriate and without independent investigation upon statements and representations of officers and other representatives of the Issuers and others.

Based upon the foregoing, and subject to the assumptions, exceptions, qualifications and limitations set forth herein, I am of the opinion that:

(1)           the Exchange Notes, when duly executed, authenticated and delivered in the form contemplated by, and in accordance with the terms of, the Indenture and issued and delivered as contemplated by the prospectus included in the Registration Statement, will be legal, valid and binding obligations of the Company; and

(2)           the Guarantees are legal, valid and binding obligations of the Guarantors.

The opinions set forth herein are subject to the following assumptions, qualifications, limitations and exceptions:

A.           I render no opinion herein as to matters involving the laws of any jurisdiction other than the (i) substantive laws of the State of New York (without reference to choice-of-law rules), (ii) General Corporation Law of the State of Delaware, (iii) Delaware Limited Liability Company Act, (iv) California General Corporation Law, (v) Colorado Business Corporations Act, (vi) Colorado Limited Liability Company Act, (vii) Florida Business Corporation Act, (viii) Georgia Business Corporation Code, (ix) Indiana Business Flexibility Act, (x) Maryland General Corporation Law, (xi) Massachusetts Business Corporation Act, (xii) North Carolina Business Corporation Act, (xiii) Virginia Stock Corporation Act, (xiv) Alberta Partnership Act, (xv) Nova Scotia Companies Act, and  (xvi) laws of the United States of America.

B.           My opinions are subject to (i) the effect of any bankruptcy, insolvency, reorganization, moratorium, arrangement or similar laws affecting the rights and remedies of creditors generally (including the effect of statutory or other laws regarding fraudulent transfers or preferential transfers), (ii) general principles of equity, including concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance, injunctive relief or other equitable remedies, regardless of whether enforceability is considered in a proceeding in equity or at law, and (iii) an implied covenant of good faith and fair dealing.

C.           I express no opinion regarding the effectiveness of (i) any waiver of stay, extension or usury laws or of unknown future rights, (ii) provisions relating to indemnification or contribution, to the extent such provisions may be contrary to public policy or federal or state securities laws, (iii) any provision that would require payment of any unamortized original issue discount (including any original issue discount at which the old securities were issued), or (iv) any purported fraudulent transfer “savings” clause.

I hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement and the reference to me under the caption “Legal Matters” in the Registration Statement and the prospectus that forms a part thereof.   In giving such consent, I do not hereby admit that I am acting within the category of persons whose consent is required under Section 7 of the Securities Act or the rules or regulations of the Commission thereunder.

Very truly yours,

/s/  Timothy M. Davis
